About Open Close Door
Open Close Door is a story-driven retro FPS in pixel art style that takes you back to the golden age of 90s shooters — but with its own narrative, dark atmosphere, and relentless pace.
You play as a secret agent who receives an urgent call from Doctor Hemlock. From the depths of an abandoned laboratory comes a chilling message: your wife might still be alive. But the truth is darker than you can imagine.
Descend into a complex filled with mutants, inhuman experiments, and deadly traps. Fight your way through 10 unique levels, each featuring comic-style cutscenes, interactions, and shocking revelations.
The game combines fast-paced action with story moments — shoot, explore, and survive to uncover what’s hidden behind the locked doors.

💬 Developer’s Note
Open Close Door is an indie project I’m creating alone in my free time — purely out of love for classic retro FPS games. Don’t expect a massive AAA production, but if you appreciate the authentic atmosphere of 90s shooters and handcrafted content, I believe this game will grab you. Every wishlist and bit of support means a lot to me. 🙏
