Effective Immediately
Shoot your way out of a collapsing office nightmare as a burned-out worker.
About Effective Immediately
Effective Immediately turns a bad job into a first-person shooter. You play a burned-out worker fighting through the twisted spaces of a surreal, decaying corporate office, trying to escape before the system consumes him.
The look mixes 2D animated characters with breakable 3D office props, all in a comic-book horror style. According to the creator, it was built with Codex on Three.js, which handles the breakable props and the flat characters in one 3D space. It placed 25th of 945 at Vibe Jam 2026.
The pace is fast and violent, in the spirit of old browser shooters. Workplace pressure is made literal here, and the sense of losing your mind under a controlling employer drives the mood while you shoot your way out of the collapsing office.
