I Am Not the Demon King Launches on Steam with 27 Characters, 72 Weapons

I Am Not the Demon King launched its full release on Steam today, 2026-08-06, and the game is launching both its single-player mode and two-player online co-op at the same time. According to the Steam release details, the full version unlocks everything at once: 27 characters, 72 weapons, six main chapters, and 23 explorable maps.

That is a sizeable package for a launch build. A top-down bullet-hell roguelike lives or dies on pacing and positioning, and once the character roles start to diverge, the build options open up fast. The real question here is whether the structure makes those numbers matter, instead of just padding the page.

What stands out more is the roguelike build feel. Random buffs, item choices, and character-and-weapon pairings are all part of the loop, so every run asks you to retune the machine from scratch. The game also adds 16 custom corruption difficulties, so there is something here for players who want a gentler clear and for those chasing a tougher challenge.

Co-op is an obvious plus for this kind of game. Two players can coordinate, complement each other’s tactics, and handle enemy fire together more comfortably than solo play often allows. As for value, the launch discount is simple: 29.7 yuan for 14 days. There will also be launch-day activities, and if you run into issues while playing, the official QQ group 2151021832 is there for contact.

If you already like reruns and build-making, I Am Not the Demon King should give you plenty of variables and enough execution pressure to stay honest. Solo players should have enough room to slowly grind out a build, while co-op players may get more out of the game’s teamwork rhythm.
