Here are ten TF2 kill clips to make you go "whaaaat," courtesy of CommFT. They've taken the best of all the kill replays submitted to the Extelevision site during December and ordered them according to their awesomeness. The list features some blinding kill streaks, a jammy but spectacular reflected grenade triple-kill, a remarkable string of headshots and a stunning three-rocket juggle kill. The list demonstrates how TF2's calamitous physics can result in some baffling mid-air encounters. Only the very best players can exploit these to earn game-winning ubers and vital kills. It's fantastic to watch.
