GUG is a sandbox simulation roguelike where you generate monsters—”gugs”—by typing any word or phrase. Your choice of words determines how they look, behave and battle. Type “banana flamethrower” and you might get a spiky yellow pyromaniac. Type “emotional support gremlin” and get… Well, who really knows?

Every word wields unexpected power, so experiment and see what incredibly broken gugs you can concoct.

Each run throws you into a new procedurally generated arena—lava jungles, haunted car parks, algorithmic chaos pits—and challenges you to create a truly unpredictable squad of gugs. You will:

Adapt to randomised rules, enemy types and objectives
Tweak your team’s strategy to seize victory or fail gloriously
Unlock new modifiers, environments and gug abilities
Ask yourself why your tank explodes when it gets healed

Gugs don’t just look weird—they work weird, too. Each creature evolves both visually and logically.

Mix and match brains, attacks, movement styles and passives across different gugs
Use procedural logic systems to combine effects in strategic—or utterly unhinged—ways
Watch unexpected synergies emerge, then break them when your next bright idea goes disastrously wrong

Whether you’re a strategy min-maxer or an architect of chaos, GUG rewards curiosity and punishes overconfidence.

The GUGverse is shared. Gugs you make might show up in someone else’s game. Another player’s fearsome "Toilet Cactus" might just ruin your whole run—and appetite. Every new gug makes the game bigger and more unpredictable for everyone.

Encounter gugs made by other players
Upload and share your best/worst creations
Join regular challenges and gug hunt bounties
Break the meta or break the game—we welcome both

This isn’t a card game. It’s not your standard autobattler. It’s not a serious roguelike. GUG is GUG: a creature collector where the gugs are ludicrous, the logic is real, and your new arch-nemesis might be “Mildly Upset Pigeon”.
