Metro Anomaly One bullet, one guess

Every clerk in the office is a suspect, and the tell can be almost nothing: a head that turns a little too far, a joint bent the wrong way. So you watch. You compare one person's walk to the next, wait for a slip, and try not to stare at the wrong stranger, because some anomalies stare back. Others do worse than stare. The game keeps the pressure on in a simple way: you get one bullet per cycle. Identify the anomaly, aim, and shoot. Guess wrong, and the thing you missed comes at you instead. It is a tense loop of observation and doubt, where the scariest moment is not the monster but the decision.
