Yeah, sure. But first lemme show you something fun you can do with it:
I present to you, the Zombie Defense mini-game!
Simply set up a few rows with tunnels, stick a soldier of your choice in each tunnel, and defend your brain for as long as you can!
I used heavy coalition soldiers with M16s and Glocks. I would recommend tossing in light diggers as well (can clean up rubble and gore, but won't damage bunker walls. Also good for a close-range gibbing), and if I were to do it over again I'd use DEagles instead of Glocks.
Here's what I've written:

Go int Missions.rte, find the Activities.ini file, scroll down until you reach the vanilla skirmish defense game mode, and replace it with this (make a backup beforehand, of course).
Also, I need to work with the skeletons a bit more... They easily bring down the most defenders (and defenses), just by getting shot and blowing up with all those stick grenades. There's nothing you can do when a skeleton hops down right in front of you and you're hemmed in on both sides by drop crates. Maybe I should change them to pineapple grenades or something...
A really cool thing would be to use brain units and play a variation of this with four players. But there'd have to be some changes, otherwise people would basically just have to "wait their turn" to shoot some zombies.
