Map19: Radical Train Part II (Prodoomer)

The same strategies as in the previous level apply here as well.

Average Payout: 3,000 credits

Secrets
1. At the very beginning, double jump on top of the light post and walk into the secret compartment to get some backpacks.

2. In the car with the two sentry turrets and the scourge, check the compartment that held the north turret for a switch. Go back to the previous car and the path to the northwest will have opened. (This must be done before triggering the tornado arch-vile.)

3. In the car after the mini-boss, with stairs full of ammo going up both sides, check the northeast corner for a secret. A couple of enemies are also in here.

Rings
36 Underneath the front of the cargo car with the vats of nukage, you'll see this ring floating just above the ground. You'll have to drop down and trigger your double jump so that you collect the ring instead of touching the kill floor. Getting the ring automatically teleports you to safety.
