Level 16: For Carnage, Apply Within
As you are playing this level on Total Carnage - I just know you are - it will be difficult with all those Compilers and Enforcers. The exit path is easy but on the other hand, it is also rewarding to go looking for those little extras...

As you arrive look up. In the ceiling is a trap. As you walk under it will drop down and trap you with a group of Enforcers. Solution? Run through it, let the Enforcers drop down and wait for the trap to reset. When it does just blast away with your guns.

If you do decide to do a bit of exploring then at the far end of the Alien Goo there's a Save Terminal and a re-charger. Durandal is also nice enough to provide you with some ammo...

After deciding to leave this level make your way up the stairs. Keep running until you reach this door. On the other side is the terminal you seek...
