Enter the Gungeon is a bullet hell dungeon crawler by Dodge Roll, published by Devolver Digital and released on 5 April 2016. Four misfits descend through a gun shaped fortress looking for a weapon that can kill their own past, and the run gives them over 200 guns and hundreds of items to find on the way down. Every room is a bullet pattern puzzle solved with a dodge roll that grants brief invulnerability and a blank that wipes projectiles off the screen. Runs last roughly 30 to 60 minutes, nothing carries over except permanent unlocks bought with Hegemony Credits, and the difficulty curve is famously steep.
Boss fights are where Enter the Gungeon tests everything you've learned. This guide covers strategies for bosses across all areas, organized by progression order. For general combat techniques, see our combat guide.
