How AI is used

"I just wanted a marshmallow." is made by one human, with ideas from other humans, and help from an AI assistant. What the AI does: it writes code and decorates maps, 3D models, effects, menus and in-game text piece by piece with Unreal's own tools, not with image or 3D generators. Various sound effects (for example, thunder and wind gusts) were made with an AI sound generator. What's not AI: voices or music, the logo, various 3D assets and effects from creators, other 3D models hand-made by the human, and the general concept that originated from the human's dream. The human built the foundation alone over months of late nights (the round flow, the original mutator director, the weapon models and a stable prototype), decides what gets added, cut or changed, and plays the builds to catch as many issues as they can. The mutator ideas come from the humans, so the compactor squishing you is fully sanctioned by the minds of the humans. No AI runs while you play.

The developer's own words, from Steam.

About I just wanted a marshmallow.

You wanted a marshmallow, and everyone ate them. They have wronged you on a level you never thought possible. You have decided to take your issues into the back. This is your story.

Deathmatch: Party Edition

Fight: Grab a weapon and rack up those eliminations.
Survive the gauntlet: The game will throw events, effects, and objectives randomly into your rounds, tipping the scales that may have been in your favour. While some may target your friends, some will target you.
Win the finale: The arena isn't the only battle. Duke it out in unique finales from boss fights to death races to score big points enough to propel yourself to the top of the leaderboard.
Two ways to win: You may take the finale, or you may take the points. Can you take both?

Nothing Stays Fair For Long

From graveyard shifts to Giant Mode, and from the ice rink to low gravity, 30 mutators are waiting to crash your round. A black hole might open up right beside you, a cruise missile might chase you across the map, or you might get stuck holding the Hot Potato with nobody close enough to pass it to. Embrace the chaos, don't run from it.

Death Is Part of the Game

Got taken out? Pay 'em back. Every few deaths, you are offered a gift: pick one of three disasters and send it to whoever you please. Everyone sees it coming except them, and everyone will know it was you. Make it count.

Hang Out At Camp

Between matches, the lobby is yours to mess around in. Grill some burgers, brew a coffee, warm up on the shooting range, or ring the cowbell and set a pack of gunners loose on your friends. We won't judge.

Earn Your Colours

Every weapon has its own unlock track. Rack up eliminations with it to unlock Matte, Metallic and Emissive finishes, and Emissive lights up your bullets to match. Clear a tier to earn its mastery skin.
