Dodge Roll and Devolver Digital announced Enter the Gungeon 2 today, teased during the Nintendo Switch 2 event and it's coming to Steam as well in 2026.
The first game is truly a blast to play through, so I'm definitely keen to see more on it. This new 3D style looks like it will make it seriously intense too, at least from the short teaser that was shown off.

From the press release:
Enter the Gungeon 2 is a reloaded, high-caliber sequel to the iconic bullet hell dungeon crawler, reinforced with a new 3D art style, new weapons and enemies, and expanded gameplay.
Battle through areas familiar and unknown as the ruined Gungeon reveals its secrets to those brave enough to enter. Discover, unlock, and master fantastic weaponry within its procedurally generated halls and destroy the legions of Gundead pouring forth from within. Charge into dynamic battles against devilishly cute enemies, previously confined to the 2D plane, and delight as they are knocked around, tossed into the air, and thrown deep into pits.
Choose from an expanding roster of Gungeoneers full of both familiar and new faces as you rescue and extract marooned heroes from the depths of the Gungeon. Become mighty through unexpected combinations of powerful passive items, explosive active items, blessings, curses, and your own mastery over an impressive armory of weapons.
And seek to understand why you find yourself under assault in the Gungeon once again...
