- Beside the Gold key door, is a painting in a red light: it's a fake one, so jump into it to get the secret.
- Near the location of the Green key are 3 portraits lined on the wall. Jump into the middle one (it's fake), and follow the small corridor to see a Rail gun. Jump to it to get the secret.
- In the room where you obtain the Gold key, one of the corners has a switch and a machinery wall in the back. Open this wall to open the secret area. Inside, walk into the blue light to be teleported to the Missile Launcher that could be seen earlier locked in a room with small pillars.
- At the end of the level, when you reach the train, before entering it, go to its back and walk along the train tracks. Soon you'll see some enemies in a short ledge. Jump to the ledge through a small window to get the secret.
- Because of train used in the level fans have given this level 'Bullet Train' name.
