I used Timesplitters Future Perfect's Mapmaker program to design this "story" map. The game lets you basically create your own level. I made a zombie survival type scenario where I only have a slowly reloading shotgun to defend myself against a zombie onslaught. The longer I survive the more zombies spawn to kill me. If I survive long enough some crazy dude will pop out and light everything on fire. I think it turned out pretty well considering the limitations of the mapmaker program. Check out the video of me playing it by clicking the preview pictures or the link.
