About Boss Up

Boss Up is a bullet hell boss rush starring Roger, a dodge-rolling horse who dreams of winning the VZN tournament and earning his own Boss Form. He faces a brutal series of fights on his way to becoming a videogame boss.

Boss fights

You take on 18 boss fights, with opponents drawn from different kinds of videogames: a 90s kart racer, a rejected mascot horror villain and a dating sim featuring Roger’s ex-wife. Each fight brings in gameplay twists from its genre, so the challenges vary from boss to boss.

Weapons and perks

You can unlock over 20 weapons and choose from several silly hats that grant combat perks. Between fights, you can grab a drink with your foes and hear their gossip. Defeat bosses without taking damage to earn P Ranks.
