This is a pretty much an arena area, which on higher difficulties can prove quite difficult.
Make sure you buy several health packs and quite a bit of your chosen ammo.
The area after your first checkpoint is where things will start to get tough, and while short, it can kill you pretty quick. Make sure to utilize the red canisters on the lurkers after the checkpoint. they will be on the right side of the drill before the checkpoint, and near the second lurker area along with a health pack. The lurkers will appear to the left side of the drill in packs of three.
This is also an easy area to get the another acheivement for using a necros arm to stick a necro on a wall. do this on one of the lurkers .
