On this page, some secrets of the level are given away. Because I envy the players who start their patrol unsuspectingly, I hide a few things under a "Spoiler" button to prevent spoiling the surprises accidently.
SECRETS:
There are ten secret areas in Wadings pumping station (nine in the original version). You
don't need to find them to successfully get to the exit. In most of them the bonus
matches the malus, so they give you more chances to fight and perish. Some of the secrets
are nested, meaning you have to get in one area to be enable entrance to the other. I will
give away here that the entrance to the heavy armory is the most difficult to
crack.
There are some hidden corners and little rooms with a bonus that do not count as a secret.
