Ah, a nice, simple level, with lots of ammo to collect. And, dare I say, deja vu? This level is obviously based on the classic Waldo's World from Marathon.
Unfortunately, the only way to exit this level is in a cooperative game: there is a switch in one of the side rooms that will open a door in another side room, but only for a few seconds; nowhere near enough time for a solo player to get from the switch to the doorway. However, this level is best accessed via a cooperative method from Rise Robot Rise (2), so this is not a problem.
Make sure that, in your cooperative game, that you grab the two access chips lying on the ledges - you can activate a secret on Poor Yurick (3) with them. Remember, each player can only carry one uplink chip.
There are no known secrets on this level.
