Probably one of my favorite things to do in CE is to try and find different ways to go through a level.
On the silent cartographer level did you know that if you Co-Op and take all 3 warthogs over to the door that the sword elite is in, you can get 2 of the hogs through. If you go fast enough the first time it is possible to even skip having to go unlock the door. but then you have no reason to take the warthog to fight the hunters over in the security room =). it’s fun to take vehicles where they aren’t really supposed to go but what are some other fun ways to go through the rest of the campaign?
