About Full Stacked
Every round, the game changes.
Full Stacked is a fast-paced multiplayer FPS where every round you draft powerful cards that warp the rules of combat. Stack explosive rounds with homing bullets. Combine a grappling hook dash with featherfall. Turn your shield into a body-swapping teleporter.
Build Your Loadout, Break the Game
After each round, pick from a hand of cards that permanently modify your abilities for the rest of the match. Simple stat boosts? Sure. But legendary cards let you steer bullets mid-flight, respawn from the dead, or turn your shield into a gravity well that pulls enemies in. Cards stack, cards combo, and the right picks at the right time can turn a losing match into an unstoppable run.
Fast, Fluid Combat
Dash through danger. Raise your shield at the last second. Crouch, slide, and double-jump across different maps. Different weapons each play differently: burst rifles for mid-range pressure, snipers for patient picks, grenade launchers for area denial, and trusty pistol.
Play Your Way
Jump into Free-For-All or team up in 2v2 matches with up to 4 players. Hosts can tweak everything — wins needed, cards offered per round, map rotation, available weapons, and more. Quick brawls or long strategic series, you set the stakes.
