To piss people off in ET: simple. For some reason, clan members hate the panzerfaust. Just start killing shit with the panzerfaust and they'll explode! I played ET because mostly... well... I'm too... cheap to buy something like Counterstrike.
You'll even get kicked by admins that'll spawnkill on a "no spawnkill" server! It's like wtf? He's pulling some shit and he goes kicking me with "get rid of that gay panzer!" (Of course these morons don't know that a panzer is a tank)
