Not sure what you call wall jumping, but you can walldodge + double boost, so I guess that complies as wall jumping?
Just checked out XMP again, it does have wall dodging even though it feels uhm sluggish. The double Jump though feels good.
As for the sprinting, it brings you to the level of UT3's default speed.
Also notices the bursts are short and you can still aim.
BTW anyone here actually tried the Crucible mod yet?
