Short for Competitive Team Fortress 2. In North
America this typically means anything going on with ESEA'
s 6v6 League and to a lesser extent UGC'
s Highlander. Comp TF2 is (un?)known for its relative seclusion from the rest of TF2, with few of TF2'
s Massive Playerbase aware that it even exists, and even fewer willing to make the
jump from Pubs to Comp themselves. This is in contrast to Valve'
s other multiplayer games such as Counter-Strike and DOTA 2, where the "pros" (or at least the teams they belong to) are well-known to the typical player.
