In The Future, There Is Only Team Fortress 2

Team Fortress...Warhammer 40K...two very different beasts, but bring them together and you've got...a very different beast.

This clip shows a work-in-progress skin pack for Team Fortress 2, bringing Space Marines to the dusty battlefields of Valve's shooter.

It may look a little strange to see the big guys running around wooden barns at such a speed, but when the Emperor calls, the Space Marines must answer.
