How to Play Gatekeeper

Learning how to play the Gatekeeper game requires sharp eyes and quick decision-making. You start your shift at the retro terminal, managing three main viewing tabs: the Window, the Camera, and the ID File. When a visitor arrives, cross-reference their physical appearance with their official documents. Look for bizarre behaviors or inconsistencies that reveal they are an anomaly. Once you have gathered enough evidence, use the action buttons to Pass, Quarantine, or Kill the entity. Be careful, as making the wrong choice or failing quick time events will increase your radiation meter. If this health bar maxes out, your run is over. As you progress through the week, the challenges escalate with flying objects and unexpected jump scares. Pay close attention to the shifting rules each day to survive your shift.

Tips & Tricks for Gatekeeper

Surviving all seven days in this anomaly horror game is no easy task. First, always memorize the daily rule changes, as the criteria for anomalies shift constantly. Second, keep a close eye on the camera feed. Some monsters only reveal their true, terrifying forms when you look through the lens. Third, manage your radiation meter carefully. Do not rush your decisions, because wrongful kills or passes will heavily penalize your health. Finally, stay alert for sudden quick time events where you must dodge incoming threats.
