If you grab the armor, beware of a Mutant chasing you. There are lots of goodies up here when the coast is clear. Then jump into the water to find two more secrets - a Mega-Health pack at the bottom and two doors on the ledge. One of them has a broken wall you can squeeze into (if you crouch) to find a Grenade Launcher and some health, while the other door leads to a trap with a Hyperblaster. If you fall in, use the stairs to get out, otherwise, be careful not to drop into the pit with spikes.
