Shotgun Trial

Shotgun Trial is a timed trial where the goal is to complete the level as quickly as possible with only the Shotgun. It is unlocked after completing Wretch and was the final level in the closed beta. A secret exit can unlock Shredder Trial much earlier than usual.

Secrets

 * 1) At the red ramp, climb up it. Reward: Automap
 * 2) Before jumping into the exit hole, look to the left for a hidden ledge. Reward: Large Rocket Ammo
 * 3) Next to secret 2 is a ramp that leads to more enemies. No reward is given.

Secret Exit : Right after the first secret, shoot the two targets to open the door. Right at the entrance to the red tunnel, there is a panel missing. Drop onto the ledge and head through the door. Unlocks: Path to Shredder Trial
