Enter the Gungeon

Enter the Gungeon is a bullet hell roguelike game developed by Dodge Roll and published by Devolver Digital. It follows four adventurers as they descend into the Gungeon to find a gun to kill their past.

Gameplay
Enter the Gungeon is a fast-paced bullet hell shooter with roguelike elements, and is therefore often compared to The Binding of Isaac. The player chooses between the four protagonists, all who have different special abilities, such as calling for support or lockpicking chests. A second player is able to join in for co-op mode and control a fifth character. While the player descends the Gungeon, they are set to go through multiple floors, each with a random number of rooms in it. While the rooms are pre-defined, the constellation of rooms in a floor, the enemies that appear in the rooms, and treasure are procedurally generated. Each room contains a set of enemies, which vary in strength, endurance, and attack behaviour, where the attack can range from simple, straightforward shots to a complicated mixture of shots fired at the same time. The player may dodge attacks by performing a dodge roll, which was inspired by the Souls series of video games, and are invulnerable during the action, or alternatively flip tables and use them as covers, although tables can be destroyed if they are shot at. The player has a limited number of "blanks" for each floor that can be used to eliminate all current projectiles and temporarily stun enemies. To defeat enemies, the player must use guns, which can be found in chests, won by defeating bosses, or bought at shops scattered around the floors in the Gungeon. The game features over 200 different guns and items that can be combined to achieve more powerful effects. At the end of each floor, a boss awaits the player; beating the boss grants the a player gun or item and currency to spend at shops and unlocks the next floor.

As the player progresses through multiple playthroughs, they may encounter non-player characters that can be rescued from the Gungeon. Once rescued, these characters take residence at the Breach, a safe level above the Gungeon, and where the player, prior to starting a new playthrough, can spend a type of in-game currency earned from boss fights to permanently unlock special items that will then have a chance of appearing within the Gungeon for all subsequent playthroughs.

Plot
Enter the Gungeon is set on a distant planet inhabited by living bullets and other strange lifeforms. A gun that could kill the past itself was kept deep within a grim fortress, until a deadly force tore the fortress down and reduced it to ashes. The fortress was rebuilt with the highest of security measures and six adventurers, each with their own stories and regrets, decide to enter the fortress and descend into the Gungeon to seek the legendary gun in order to defeat their own past.
