In Kill The Heroes, the guy wakes up in a secret facility that seems oddly familiar. The room is littered with plans to take over the world. The guy then suddenly thinks that he lost his memory, and that he is actually a supervillain mastermind that will conquer the globe, but during his daydreaming, alarms set off. There was a breach in the facility. Heroes are coming in, and you should eliminate them with turrets and a bit of manual labor, which means you have to shoot them yourself. The way the hero goes are indicated in the path so you know where he is moving.
