Side secrets
As a Survival map, Exit 115 has no main quest and no Easter egg to complete. What it keeps from Ashes of the Damned are a few side secrets:
The vending machine
Outside McDougal’s Service Station. Once every round, a melee on the bottom of the machine while crouched makes it drop a random item. A punch with the Melee Macchiato fist destroys it: it throws out a large pile of items at once, and stays broken for the rest of the game.
Free Bonus Points
A Bonus Points power-up lies on the underside of a car, on the collapsed middle section of the highway bridge.
Chompy
Behind the diner, by the dumpsters. It takes a weapon or a piece of equipment and pays back Salvage, sometimes equipment or a wonder weapon; fed ten Monkey Bombs, it always gives a Ray Gun. It never takes the melee weapon or the Necrofluid Gauntlet.
Mister Peeks headphones
A pair sits in a jeep near the gas station. On Ashes of the Damned they are one of the three sets that start the song Turn to Ashes.
