What changed in Enter the Gungeon in 2019

Hidden features of items have been largely made explicit in the Ammonomicon entries.

Boss health bars now turn transparent when the player is under them.

Includes items like the Fat Line and the Ticket to the Gun Show.

Players can now control two new secret characters: the randomized Paradox and another mysterious character.

Many guns and items have received buffs, making red chests more consistently good.

Explore a new secret area filled with new enemies and face off against a unique new boss.

Alternative costumes for characters are now complete.

A community-inspired mode where each floor drops a rainbow chest, allowing players to pick one item per floor.

Fixed a bug where players could get an unhealthy amount of wall mimics after playing many runs.

Notable performance improvements, especially on the Switch version.
