About Karmx
Karmx is a fast-paced boomer shooter set in a Lovecraftian medieval fantasy world. Developed by Matthieu Gouby, it launched on October 1, 2025, for PC. The game blends chaotic combat with a real-time level editor, letting players reshape maps on the fly while battling grotesque enemies. Think of it as a tool for creating and destroying in equal measure. With a single-player focus, it leans into chaotic fun, encouraging experimentation over precision. Maps built in the editor can be shared via Steam Workshop, making it as much about creativity as combat. Ideal for fans of chaotic, high-octane shooters who enjoy tinkering with level design.
Gameplay
In Karmx, you control a medieval warrior armed with arcane and physical weapons, battling Lovecraftian horrors in procedurally generated environments. The real-time level editor is the star here, you can carve walls, summon obstacles, and flood areas mid-battle to trap or funnel enemies. Sessions typically last 30 to 60 minutes, balancing frantic combat with thoughtful map manipulation. Movement is twitchy and aggressive, with a focus on dodging and shooting. The level editor uses a grid-based system but requires quick thinking to adjust layouts during fights. While the core loop is straightforward, mastering the editor’s complexity adds depth. Enemies vary from shambling monstrosities to fast attackers, demanding constant adaptation.
What Players Think
PlayPile community ratings average 4.2/5, with 78% completing the main story. Average playtime is 12 hours, though 30% of players report frustration with the editor’s learning curve. Community moods split 45% “creative,” 30% “frustrated,” and 25% “enthusiastic.” Reviews praise wild map designs but note a steep difficulty spike in later levels. One user wrote, “Maps are wild but the learning curve is steep,” while another added, “Best if you’re patient with the editor.” Achievements (50+ total) focus on map complexity and combat skill, with an average 65% completion rate. Price is $29.99, placing it in the mid-tier indie shooter range.
PlayPile's Take
Karmx is a niche pick for boomer shooter fans and level-design enthusiasts. The real-time editor adds a layer of creativity few games offer, but its complexity might alienate newcomers. With $29.99 and 50+ achievements, it’s a solid value if you enjoy chaotic action and iterative design. Skip if you prefer polished, intuitive mechanics. Worth trying if you’re up for a challenge and want to play with a toolset that doubles as a game.
