What if your whole world was a lie? Solve clever puzzles and face incredible challenges to escape the faulty simulation that keeps you captive. Question reality and unravel a dark conspiracy while dodging security systems in this innovative puzzle-strategy adventure.
You wake up as R3D, an alien robot trapped in a strange simulation. You don’t know who controls you or why, but something doesn’t add up. Every move could bring you closer to the truth—or bury you deeper in the lie. How far are you willing to go to find the way out?
If you enjoy games that mix adventure, puzzles, and strategy, here you’ll find a unique experience. Dive into a layered story and uncover the hidden motives of each character. Follow the dialogues, discover secret notes, and use the right information to make the best decisions at key moments.

Did you manage to break the simulation? Now you’ll have to face the General to escape the laboratory. Get ready to solve new puzzles with fresh mechanics while enemies and turrets hunt you down without mercy.
Only those who relish strategic challenges and intense adventures will be able to overcome this final trial.
