Secret Exit

Secret Exits are a rare type of exit found throughout Prodeus. They unlock new routes through the campaign and occasionally new levels. Ammo Cache must be accessed three times in three different locations to unlock the Bandolier. Of these three unlocks, only one is unlocked without a secret exit.

List of Secret Exits
Sacrum: Shortly after fighting your first Fiend, a hidden ledge can be jumped to containing the first secret exit of the game. Unlocks: Portal to Citadel

Shotgun Trial: At the beginning of the red tunnel, right after the automap secret, drop down a hidden hole and go through a cave. Unlocks: Path to Shredder Trial

Chaos Generator: In the room where you first shoot the shield, jump on the rock pillar to find a hidden cave. Unlocks: Ammo Cache

Marksman: Near the level start, a small indent on the cliff face can be seen. Jump down there to find the hidden exit. Unlocks: Ammo Cache
