It's actually really annoying when people use it in this game, especially when combined with walk through walls and invincibility. Basically they just run around the map super fast and force you to turn on infinite health...I'm just happy for the moment that most of them are too stupid to use WPE Pro correctly, even with the information I put on wikipedia about the damage packet, or they'd be rapidfiring their accursed shotguns in all directions at once.
