Rat Race

Rat Race: This is one of the smaller levels and good for anyone who's handy with a Shotgun or Assault Rifle. The key to this level is to always be on the move, don't let anyone catch you with your guard down which is easy to do with all the dark corners and shadows. There is once again a teleporter network set up around the map to get around quickly (near the teleporter in the middle of the long hallway is a very dark corner and you can hide next to the teleporter without being seen, this is effective for ambushing people as the come and go through the teleporter. There is also a mined out cave leading to a teleporter and an open hole that has an invisibility power-up you can get, if you are on the ground underneath a well placed grenade can also knock the invisibility down for you to grab.
