Doublefrost - Team Fortress 2 (2007) Developer - Valve Publisher - Valve

Doublefrost is a Capture the Flag game mode map added to Team Fortress 2 during the Smissmas 2021 update. It is a seasonal version of the map Double Cross, and it is only accessible during the game's annual Smissmas event in December, altering the map to be set during the day and covering it in snow, ice and wrapped presents.

The map is composed of two opposing bases connected by a bridge over a large chasm, with a railway below that connecting the two sewer entrances found on opposite sides of the map. The objective of each team is to enter the enemy team's base in order to capture their gift-wrapped, intelligence briefcase and return it to the their own team's base. The team that does this three times first wins.

The map's two sewers have been changed so that the water has frozen over, and is also decorated with presents, but it is otherwise the same. It is accessed via the external entrance, a hatch at the bottom of each team's spawn area, a staircase near each team's spawn and by jumping down into the sewers from a hole in a small building in the outdoor courtyard behind each base. The sewers each contain a small health kit and a medium ammo crate, and can be used as an exit from the base, or a flanking route by the enemy team to sneak in.

The map also includes some added easter eggs that are not present in the default verion of the map. Behind a fence near the BLU base are two snowmen, while the behind the RED base has a row of reindeer cut-outs, one of which references Rudolph the Red-Nosed Reindeer. The maps near the Intelligence have been changed to be tracking a reindeer and possibly a yeti, and scattered around there are a number of toy trains, referencing one of the map maker's other maps, Trainsawlaser.

SnowVille - Team Fortress 2 Developer - Valve Publisher - Valve

SnowVille is a Player Destruction map and a festive version of the map Sawmill. The map most closely resembles the King of the Hill version of Sawmill, but has been updated visually to be covered with snow and festive adornments, while removing the two sawblades in the centre of the map alongside other changes to the layout to better support the gameplay.

The objective of both teams is to kill players of the opposing team to collect the presents that they drop. These presents need to be transported to one of three capture zones in order to be added to their team's total present count. Which capture zone is the correct one is determined by whether the Smissmas sleigh being pulled by two flying Pyrobots is present, as during each capture window they will randomly appear at one of the three capture zones.

The sewer section has been radically redesigned in SnowVille, no longer being composed of boarded-up grates receiving water from a nearby waterfall or letting water flow into a drainage river. They have been expanded into underground side paths leading away from the central capture zone via a pit in one of the two cabins, and towards one of the two side Capture Zones. Despite the signs describing a dead end, it is possible to explosion jump up the pit to get to the central area. The area around the sewer exits have also be redesigned, with the water pool and river being partially frozen over with traversible ice, and a cabin that serves as a capture zone being added where the small bridge near to the removed waterfall was.

Snowville is a community-created map that was added to the game during the Smissmas 2020 update, alongside three other maps and a number of cosmetic items and taunts. Due to its seasonal theming, the map is only available to select in casual matchmaking during the annual Smissmas events.

Sawmill (King of the Hill) - Team Fortress 2 Developer - Valve Publisher - Valve

Sawmill is a map made for the King of the Hill game mode, and is based on the previously released Arena version of the map. The map is still set in the same lumberyard but has been edited to add two small health pick-ups near the central control point, upgrading and increasing the number and size of the available health and ammo pick-ups, and added a resupply locker to the spawn room.

The objective for both teams is to capture the central control point and hold it for a total of three minutes before the enemy team in order to win the round. The control point is protected by a pair of saw blades that will kill any player hit by them instantly, even if under the effects of an ÜberCharge.

The drainage river can be found on the edge of the map, and has a small wooden shack built over it that contains a medium health pickup.

Sawmill (King of the Hill) was added to the game in 2009 during the Classless update, alongside the Capture the Flag version of Sawmill and four other maps. This is the first major update to not focus on updating any class's arsenal, instead adding a large variety of cosmetics instead.

Sawmill (Capture the Flag) - Team Fortress 2 Developer - Valve Publisher - Valve

Sawmill is a map made for the Capture the Flag game mode, and is based on the previously released arena version of the map. The map is still set in the same lumberyard but has been edited to remove the central control point, replacing it with a small health pick-up and increase the number and quality of pick-ups across the map, blocking off some side paths and adding the flooded Intel Rooms for each team.

The objective for both teams is to collect the opposing team's Intelligence Briefcase and transport it back to their own Intel Room. Being killed while carrying the Intel will cause to fall on the ground where the player died, and if a member of that player's team is unable to pick it up in the next minute, it will respawn in the Intel Room it came from. The first team to capture the Intelligence three times will win the round.

The drainage river can be found on the edge of the map, and has a small wooden shack built over it that contains a medium health pickup.

Sawmill (Capture the Flag) was added to the game in 2009 during the Classless update, alongside the King of the Hill version of Sawmill and four other maps. This is the first major update to not focus on updating any specific class's arsenal, instead adding a large variety of cosmetics instead.

Dustbowl - Team Fortress 2 Developer - Valve Publisher - Valve

Dustbowl is a map made for the Attack/Defend game mode, and is based on the version of the map found in Team Fortress Classic. Dustbowl is set in a coal mine that has been repurposed to house a network of competing spy bases that surround a rocket launch site.

The objective of the BLU team is to capture all of the map's control points that are being defended by the red team before the round timer counts down to zero. The map is divided into three stages, with each stage being split between two control points that must be captured in a linear order, and capturing a control point gives the BLU team additional time to beat the level. The RED team meanwhile is tasked with stalling the BLU team's advance long enough for the timer to run out, winning them the game.

The drainage channel can be found below the bridge leading to the final control point, and can be entered by jumping down into it or using the flank tunnel that begins near BLU team's side of the map. The only ways out of the sewerage system is by heading down the tunnel, using the narrow staircase that has an ammo crate at the top or by explosion-jumping back up.

Dustbowl was one of the first six maps in the game when it first launched in 2007. It was originally described as a Control Point map, but has since been reclassified as an Attack/Defend map. Dustbowl is also the only map in the game to have a training mode, where a new player can be joined by bots scripted to behave and spawn in specific numbers and classes in order to help the player understand the game. The training mode version of dustbowl has an identical layout and set of objectives and was added to the game in 2010 during the Mac Update that brought TF2 to macOS.

Sawmill (Arena) - Team Fortress 2 Developer - Valve Publisher - Valve

Sawmill is an Arena map, set in an abandoned lumberyard with a sawmill in its centre. The objective of both teams is to either kill all the player's on the opposing team or to capture the control point at the centre of the map when it unlocks a minute into the match. Unlike most other game modes, players do not respawn on death leading to shorter matches.

The drainage river can be found on the edge of the map, and has a small wooden shack built over it that contains a small health pickup.

The map was added to the game during the Sniper vs. Spy Update in 2009. This update came with new weapons for the Sniper and the Spy classes, a new game mode called Payload Race, three other maps and the addition of unlockable hats.

Wutville - Team Fortress 2 Developer - Valve Publisher - Valve

Wutville is a community-created Payload map and was added to the game during the Smissmas 2020 update, and is set in a Christmas-themed penal labour camp. The objective of the BLU team is to escort the train carrying a bomb to the final terminus, blowing up the facility before the round timer ends. There is a total of four checkpoints, reaching the first three grants the BLU team additional time, giving them more time to reach the last checkpoint and win the round. The RED team meanwhile is tasked with preventing this by contesting the payload and killing the BLU team mercenaries to stop them from pushing forward.

The map has many sewer tunnels, the first two connect the initial BLU team spawn rooms to the map, while the rest can be found around the map, serving as flank routes around the open main path.

The map's name and design is a reference to the version of Whoville found in How the Grinch Stole Christmas! by Dr Seuss. Wutville is only playable during the annual Smissmas event that starts on the 1st of December, and ends on the 7th of January.

Citadel - Team Fortress 2 Developer - Valve Publisher - Valve

Citadel is a Payload map and is set in an old coastal village below a castle that has been taken over by the RED team to repurpose it as a facility housing a massive lightning rod.

The objective of the BLU team is to escort the payload tank to this lightning rod in order to destroy it before the round timer runs out. There are five checkpoints along the way, each awarding additional time to the BLU team for reaching them except for the fifth and final checkpoint that grants the BLU team victory. The RED team meanwhile is tasked with preventing this by contesting the payload and killing the BLU team mercenaries to stop them from pushing forward.

The tank is much larger than the usual payload carts and as a result the BLU Engineers can also place their buildings on top of it. Due to its size however there are places where it can crush players against walls or corners, and as a result of bugs, it is possible to become stuck inside sentries and other buildings on top of it, or to become stuck inside the tank itself freezing it in place.

The storm drain can be found between Checkpoints B and C, with the outflow serving as a moat beneath the drawbridge. Next to the sewer is a narrow staircase that can be used as a flank or escape route.

Citadel is a community-created map and was added to the game during the Summer 2025 Update. The map also has an easter egg, in the BLU spawn room there is a Drinking Bird toy that can be found bobbing on the shelves.

Badlands (Arena) - Team Fortress 2 Developer - Valve Publisher - Valve

Badlands is a an Arena map, created as a modified version of the Control Point map Badlands that released a few months earlier. The map focuses on the central control point removing the other four, and makes other adjustments to map to better suit the arena game mode, while retaining the setting of a gravel mine, and keeping the map largely recognisable. The objective of both teams is to either kill all the player's on the opposing team or to capture the control point at the centre of the map when it unlocks a minute into the match. Unlike most other game modes, players do not respawn on death leading to shorter matches.

The sewers can be found in the corner of the map as a drainage basin. Unlike the Control Point version it has water so players can extinguish themselves and has a fence in the back blocking off the flank path, in order to close off the map and encourage fights.

Badlands was added to the game in 2008 as part of the Heavy Update, which added the Arena game mode and the first five arena maps, Ravine and Lumberyard, as well as modified Arena versions of Well, Badlands and Granary.

Gold Rush - Team Fortress 2 (2007) Developer - Valve Publisher - Valve

Gold Rush is a Payload map, set in a Badlands gold mine that houses a network of secret spy bases. The objective of the BLU team is to push the bomb cart to the end of each stage within the time limit, gaining additional time for each checkpoint they pass along the way, the time remaining at the end of the stage is added to the time available in the next stage. The RED team is tasked with preventing this by killing and obstructing the enemy players to prevent the BLU team from taking the bomb to their final spawn base and blowing it up.

The map is covered in drainage channels, leading into storm drains. These channels are used primary routes the bomb is pushed along, or as flank routes running around and under the main path.

Gold Rush was developed by Valve and added to the game during the Gold Rush Update in 2008. It was the first map made for the Payload Game Mode, and was also the first new map to be added to the game besides the six available from launch and discounting the modified versions of Well and Badlands made for other game modes. The map began development as a remake of the Team Fortress Classic map Dustbowl, however the developers ultimately decided to create a version of Dustbowl more faithful to the original that was added to the game on launch, while Dustbowl 2 was reworked into Gold Rush.

MAP02: Underhalls - Doom II (1994) Developer - Id Software Publisher - GT Interactive Software

Underhalls is the second level of Doom II and is set in a sewer system on Earth that the Doom Marine travels through in order to reach the Spaceport. Throughout the level, the player will have contend with various demonic enemies including the rifle-wielding Zombiemen, Shotgun Guys, Fireball throwing Imps and the charging pink Demons that only appear on higher difficulties. The map is laden with explosive barrels that can be set off by the player and enemies, and contains, health pickups, armour, and ammunition.

The player is tasked with acquiring two key cards in order to reach the level exit. The first is the Red Key Card that can be found in the brick building in the courtyard that is defended by Zombiemen and Shotgun Guys. Collecting the key card however will release a second wave of enemies that will encircle the player's position, and must be dealt with before the player can safely proceed. After backtracking to the Red Door in front of the starting area (that Shotgun Guys may have teleported into) and unlocking it, the player will be able to hit a switch that opens up the route to the Blue Key Card.

The second half of the level is a corridor leading to a room with two holes in the ground. Jumping into the holes will lead the player into one of two small arenas that can quickly kill an unprepared player, but it is possible to thin the horde by shooting at enemies from above before diving in. The Blue Key Card is in the pit, and can be used to unlock the door that leads out of the pit, as well as the door to the exit room. The exit room itself is another ambush, containing a group of Shotgun Guys that will need to be dealt with quickly. Clicking on the Exit Switch brings up a scoreboard noting the percentage of enemies killed, items collected, secrets found and will compare the player's time to complete the level with the par time of one minute and thirty seconds.

Before reaching the Red Key Card arena, the player can take an optional side route. The path is blocked by Zombiemen and Shotgun Guys who are guarding the Super Shotgun, an extremely powerful weapon that can be unlocked early here and makes clearing the level, and suriving ambushes much easier. There is also a secret found by clicking on a wall to the left of the Red Key Card, opening an alcove with a blue armour pickup, some Shotgun Guys and a teleport leading to the start of the level.

The number of enemies present in the level changes depending on the game's difficulty. The I'm Too Young To Die and Hey, Not Too Rough difficulties contain twenty-one Zombiemen, five Imps and twenty-one Shotgun Guys. The Hurt Me Plenty difficulty has twenty-two Zombiemen, nine Imps, thirty-eight Shotgun Guys and a single Demon. The Ultra-Violence difficulty has twenty-two Zombiemen, sixteen Imps, fifty Shotgun Guys and two Demons. The Nightmare difficulty has the same number of monsters as Ultra-Violence, but they respawn indefinitely and move faster. The items the player can collect in the level are not impacted by the difficulty.

Upward - Team Fortress 2 (2007) Developer - Valve Publisher - Valve

Upward is a map made for the Payload game mode, and was added to the game in 2010 as part of the Engineer Update. It is set in an abandoned mining facility that was built on top of a mountain in the desert. The objective of the BLU team is push the bomb cart through the map to the fourth and final checkpoint, before the round timer runs out, while each preceding checkpoint reached gives the BLU team more time to reach their final destination. The RED team meanwhile is tasked with preventing this by contesting the payload and killing the BLU team mercenaries to stop them from pushing forward. Due to being on a mountain, the risk of falling or being pushed off a cliff is a hazard to both avoid and be used by players against the enemy.

The sewer is found underneath the RED team's first spawn room (that later on in the game serves as the BLU team's third spawn room). It is in-between Checkpoint B and C and can be used by both teams as a route connecting the spawn room exit to the battlefield.

The RED team meanwhile is tasked with preventing this by contesting the payload and killing the BLU team mercenaries to stop them from pushing forward.

The sewer is found in the BLU industries dock at the third checkpoint, and can be used as a flank or escape route to and from the fighting in the warehouse. It leads onto the beach before the fourth checkpoint.

The map was added to the game during the Smissmas 2020 update, and when the seasonal event ended, it was added to the year-round list of maps for casual matchmaking. Additionally in the first BLU spawn room, there is a small payload bomb that can be jumped onto to reach a breakable vent grate. Crawling through the vents leads to a hidden dance floor that BLU team players can socialise on.

Byre is a community-created map made for the Arena game mode. The map is set in a barnyard, with two spy bases hidden under opposite sides of the map, and a large ray gun at the map's centre pointed at a large flying saucer that looms overhead. The objective of each team is to kill all members of the opposing team or to capture both control points in order to win the game. Doing so will cause the ray gun to fire at the UFO while the match's scoreboard displays. Byre is notable for having two control points, while the rest of the Arena maps have only one.

The drainage sewers can be found to the left of each team's spawn base and serve as a flank route around the control point closest to each team's base.

The map was made as part of the TF2Maps.net Major Mapping Contest #11, "Mercs vs. Aliens" in 2014, winning third place, and was selected to be officially added to the game in the Invasion Community Update in 2015.
