you can only steal a vehicle in the first place if it has already been used by an enemy.
i liked XMP, the vehicles were alot cooler. Bigger too. it seems that models and vehicles in UT3/4 are kinda small compared to other games. Thats sucks, thats another reason its kinda hard to hit your opponents.
What's XMP? (Bring on the flamin'!)
Expanded Multiplayer, Unreal 2's multiplayer component which was released in December (if it was called EMP then things would have got really confusing :P). As a gametype it's a lot better than Onslaught, but UT2004's combat is generally better. It's being ported to UT2004, but not much has been heard about that since it was announced.
Actually I've been shot down several times by the Levi in my Raptor. Guess I'm just not good enough yet. *sighs*
