I'm starting to think weekends are better for challenges :P Shootin' and Lootin', you lot know the drill. Do all the others, them either play campaign or play Forge. The best Forge idea we've had yet is a half submerged map. But more seriously, Wraiths. Lots of them. Where There's Smoke needs no advice. For Harder Than Some, you can always use the first mission. Neuroscience, just play some SWAT. Well guys, it's a pretty good day. Have at it. Also, I don't have any pictures, sooooooooo
Here's a kirby. Enjoy
