Team Fortress 2 + Portal gun = Team Portress
Not since we've seen a DeLorean in Crysis have we been so in love with a mod. Team Portress, a 3 Point Games Community mod for Team Fortress 2, adds the iconic gun from Portal into the mix. As you'll see in the multiple videos past the break, nothing stops a Scout dead in his tracks like a nice portal trap.
Some necessary changes had to be made from how the portals usually operate. For example, there's a timer for each portal, instituted in order to keep players from being stuck in perpetual loops. Also, by reloading, you can manually kill any active portals in the game world.
