This is the unofficial Universe and Timeline Archival Project account, documenting and archiving pieces of media from alternate universes and all info on them possible. Banner from the game "Undertale" PFP from the official U/TAU youtube channel. Based on DustDustDust!Obsesion!Insanity!Killer!Killer!Horror Mr. Domino!

INTRO!!! (WIP)

This sideblog is a fanmade archival blog for the YouTube channel "Universe/Timeline Archival Unit", previously known as ShiftaSpunner.

Universe-Timeline Archival Unit

Here you can find a selection of alternate universes' video game music. I do not own the rights to any of the music heard in these videos.

They compile music from alternate universes and release them onto our planet

My job is to archive information about these universes. Some may have large amounts of writing, whilst others will have next to nothing.

If I miss anything in an AU, feel free to ask me to add it to a post.

If you desire to use the discord server and talk with others on similar AU-esque topics, join the server. https://discord.gg/NDQYnTJAWw

eyy, so what uploaded AUs in the channel do ya feel are, like, da most canon-accurate/canon-friendly out of all the other uploaded AUs?

On the channel? I’d have to say….

Either untitled tag game: halloween hack, UNDERTALE: GAMETEST_7 Build 3313, or Baba is Outer, since I feel like their existence doesnt really impact any canon the games have (for the most part)

I haven’t made their posts yet for I am working on something else atm

Plants vs. Zombies (Starter Route)

Base: Plants vs. Zombies Timeline: Weird Route

The PVZ Starter Route is a secret route within PVZ, in which you progress through the game by ONLY utilizing Peashooter (as an offense. sunflower is still allowed), no other plants. By utilizing it more and more you basically negatively influence these peashooters to become stronger for your own safety.

This is a false friendship. You try to use them more and more even if the rest of the game is not fit for peashooter planting the idea that despite the odds are stacked against them, especially if it's something impossible, you're only trying to make them grow stronger.

"We're in this together… right?"

You lose over and over, and this FORCES the Peashooter to get stronger.

Levels 1-7: fairly normal, until "peatrigger.ogg" After that, 1-10, the conveyer level has ONLY peashooter, no one else. In night levels, Peashooter's cost is halved and its shooting speed is doubled. It can also shoot in other lanes. By 2-10 Peashooter's damage is increased to 1.2x. This increases by .25 every level until 3-5 Throughout the route, Dave attempts to get you to abort the route through minigames, like in 2-5. Utilizing Cherry Bomb (or anyone else other than Peashooter) in games like whack-a-zombie is also considered an abort.

When the Big Trouble, Little Zombie minigame is supposed to play, it doesn't. Instead. Dave interferes and tries using his own plants to kill your overtuned Peashooter. Once you beat him, Peashooter unlocks the Pea Gatling ability from Garden Warfare and uses it on Dave, almost killing him, leaving him weak, pathetic, worthless. You get Dave's keys and drive off, leaving him to die.

"He'll only get in the way..."

4-10 is Zomboss. The only conveyor level to not have Peashooter. You play mostly normally, albeit a little harder. The game ends like normal, just without a music video.

If you playthrough the game again, you'll have everyone unlocked and can play like normal, just with the overtuned peashooter in your inventory now. It's mostly normal, just without Dave

The game remembers what you did. The only way to keep it from plaguing your life is to hard reset the game.

Even the tutorial remains similar... although...

1-1: "place down ONE peashooter" 1-2: "Other plants, like Sunflowers, are integral to a great defense! Try experimenting. You can't just force a strat for everything..." 3-5 (Unlock Car Keys): "You've now unlocked the shop. You felt goosebumps when you held them."

Your almanac entry for your Peashooter when the Starter Route is started.

Peashooters are your only means of defense. They shoot peas at attacking zombies.

Peashooter is your solution to any zombie-related troubles. They will always be at your service. No other plant can compare to such versatility. Two can be able to cover your full lawn! And it's all thanks to your rigorous effort and support for them that Peashooters are the gardener's go-to! After all… you're in it with them… right?

Damage: Huge

...

the tree of wisdom hates you too. "you disgust me..." "choose any other plant!" ...

it then tells you to type... "something." "something." the code. "something." typing this will permanently delete your peashooter, even starting a new save doesn't get it back. You get a puffshroom with a coffee bean.

Cost: 50 Recharge: Very Fast

Extra info: Dave dialogue

2-5

"heya heya!" "noticed you've been using peashooties alot recently" "im sorry to break to you but…" "peashooties are just not the way y'know?" "they're pratically moldy!" "use a free puff-shroom! use a powerful repeater…" "and Especially use that cherry bomb." "i know you like it when things go BOOM! BOOM! BOOM!" "and… sorry, as a CRAAZY man i tend to get sidetracked" "anyways…"

3-5

"funny thing about the…. wait a minute" "YOUR STILL USING THE PEASHOOTER?!?!" "this is getting REALLY ridiculous" "I know im CRAAAZY! but I'm not THAT Crazy!" "Im Starting to think tha YOU are a zombie!" "Because no human would plant the same plant after getting TONs of better plants!" "Y'know What! Here's a Deal!" "Were gonna play a game of "Plants vs Plants" " "If you win. you keep the peashooter. "BUT if i win. I Take away your Peashooter" "Sound Good?" [YES OR NO OPTION] [YES] "Sounds Good" "Get ready to Soil your Plants." "And they better not be peashooters!" [NO] "You just don't wanna Give them away!" "But i still have the Crazy Dave Brain" "In the Crazy Dave Brain YES means YES…" "and NO means YES!" "So Were still playing!"

After 3-5

"KEEP YOUR PEA! KEEP YOUR PEA!" "AND EVEN MY CAR PEAS!" "… I MEAN KEYS!" "JUST PLEASE NO MORE GREEN IN THE FACE!"

...5-5.

"Neighbor, listen to me." "I'm gonna tone down the crazy for a sec." "Ya do know there are OTHER plants, right?" "Ya don't have to just use the ones ya started out with." "Was it that Zombie Mood Ring I gave ya? That thing definitely looked sketchy."

(A button appears labelled "Proceed". Once clicked, the homeowner plants two Flower Pots in front of Crazy Dave.)

"Wait, what're ya doing?"

(The homeowner then plants a Torchwood down.)

"Wait a darned minute…no, ya couldn't be!"

(The homeowner then plants a peashooter behind the torchwood)

"That ain't…one of my upgrades, is it?" "Neigbor, please! I'm beggin' ya! Don't do this!"

(The "Proceed" button returns to the screen. Once the player clicks it again, Crazy Dave is blasted with flaming Gatling Pea shots, eventually falling off the roof and onto the roof of his car shop, with the sound of smashing glass followed by a car alarm being heard soon after he falls. Luckily, his scream is heard soon after he stops the car alarm, letting the homeowner know he's still alive. He then begins yelling up to the homeowner from the wreckage of his shop, unable to move due to his injuries.)

"Don't worry, bud, I'm still A-O-GOOD…" "…but my shop sure ain't."

(The level then proceeds as normal, but all seed packets aside from the starter plants' are completely gone from the menu from now on.)

the sound indicating that you're too far gone
