About the game
In Kill The Boss, you play a commander who wipes out whatever enters the arena, and as soon as one enemy falls, something even worse replaces it. You strike first, and your ninjas act without waiting for another command. The flames keep burning and the rocks keep falling, with the goal of a completely cleared yard. Pixel Camel Studios developed and published it, and it launched in 2026.
