Headcanons from my Lancer session last night, specifically about different megacorps food rations, and their overall palatability;
GMS/Union (they're basically the same thing in this case): Absolutely the bare minimum. They'll keep you alive, they'll keep you full, but they don't really taste like anything and dont exactly have a palatable consistency. I described them as "tasting pleasanty of nothing in particular", similar to Imperial Guard survival rations mentioned in the Cain books.
Once again, the absolute bare minimum.
ISP-N (Specifically in relation to my character Lyons, whos an imprint of a dead Caliban test pilot now put into a comatose cloned body, and therefor a former ISP-N employee): Think the space equivilent of Naepoleonic shipping wares for a sailor.
Yes, that includes space hardtack. You do get a couple pounds of salted meat-equivilent and a ration of booze, however, so it all balances out. Yes, space grog is on the menu. As are space-lemons to prevent future-scurvy.
SSC: You remember that little pill thing in the first Spy Kids movie? The one you shoved in the microwave and an entire McDonalds kids meal came out hot and steaming?
Thats SSC rations. You shove them into an SSC matter recombiner and you have an entire four course meal before you, including fitting wine and appertifs.
Most soldiers dont actually have to make it themselves of course, theres usually someone around to do it for them. Because this is SSC, that waiter may or may not be human. Or close to human.
(There was a 20 minute rant about cat girl maids and feet following this take that as you will)
Harrison Armory: Literally just space MREs. Lots and lots of fried meat, and jerky. Oh, and also the return of the "rat-fuck bag", because of course that would be a thing.
Just dont ask where the "mystery meat" comes from, its all labeled as originating on [REDACTED].
Horus: Since its not really a company and is more of a web presence, "rations" for Horus would consist of hacker fuel; Gamersups from a container with a waifu on it, mech-sized bags of ranch chips, and multi-gallon containers of energy drink.
Alternatively, its just raw memes shoved straight into your cranium so you need not worry about feeling hungry or thirsty at all.
