PolyMayhem is an intense top-down shooter in the survival arena genre. You stand alone against endless waves of enemies — and the only way to survive is to grow stronger mid-fight.
The game features 15 levels with escalating difficulty, from a gentle warm-up to the brutal "Impossible" mode where elite monsters flood the screen. Along the way you'll face 14 enemy types with unique behaviors: berserkers, shield chargers, bombers, necromancers that summon undead, and massive ground-slam tanks.
After each XP level-up, choose upgrade cards in four rarities — from Common to Legendary — and build devastating combinations. Between runs, spend coins in the shop on permanent upgrades for your character and weapons.
An arsenal of 12 guns awaits: pistols, shotguns, assault and sniper rifles, LMGs, and a minigun. Pair them with grenades and a dash ability — and you have everything you need to make it to the end.
