The secret room on Chapter 1.

It can be unlocked after completing the mod once, it is the first door on the left when you see the black silhouette walk away in the very beginning of the game. Also, there is a secret room at the beginning of Chapter 6 - "It's not over yet". After the train crash, search around the wrecked red car. It looks like a big iron trapdoor, that leads to an old bunker. If you attempt to open the iron trapdoor in co-op, then your character will say that only Simon can open it.
