Enter the Gungeon

Enter the Gungeon is a 2016 bullet hell roguelike video game developed by American studio Dodge Roll and published by Devolver Digital. Set in the firearms-themed Gungeon, gameplay follows several player characters called Gungeoneers as they traverse procedurally generated rooms to find a gun that can "kill the past". The Gungeoneers fight against bullet-shaped enemies, which are fought using both conventional and exotic weapons. Enter the Gungeon features a permadeath system, causing the Gungeoneers to lose all obtained items and start again from the first level upon death. Between playthroughs, players can travel to an area called the Breach, where they can converse with non-player characters and unlock new items randomly encountered while playing.
