Alien Checkpoint Simulator

Night shift at an alien facility. Screen patients, spot the anomaly, survive.

You just started the NIGHT SHIFT at a top-secret alien containment facility. Your job sounds simple: screen every incoming patient, treat them, and decide who is safe to release. But some of them are not quite… human. Welcome to Alien Anomaly — a tense mix of SIMULATION, anomaly hunting, and psychological horror where one wrong call can end the night. 🛸 SEE IT? SORT IT Every alien patient that arrives could be normal — or an ANOMALY in disguise. Use your screening tools to inspect faces, vitals, documents and behavior. Something feels off? Send them to quarantine. Miss the sign… and it gets loose. 🔬 SPOT THE DIFFERENCE, ALIEN STYLE This is spot-the-difference for the brave. A missing detail, a wrong reflection, a face that isn't quite right. If you loved anomaly hunting and observation games, you'll feel right at home — now with an extraterrestrial twist. 🌙 SURVIVE THE NIGHT SHIFT The clock never stops. Manage patients, keep the facility contained, and make choices that matter. Stay sharp: the longer the night runs, the stranger the anomalies become. 🧪 LEARN. ADAPT. SURVIVE. Unlock new tools, discover new alien anomaly types, and uncover what's really happening at the facility. Every decision shapes how your night ends — multiple endings await.
