Sweet! As mentioned some time ago, XMaps is in fact returning for UT2, and there is even a beta version out for testing if you wish.
I realize many have read this on PU or whatever already, but it's worth mentioning anyway, just in case. XMaps was by far the finest utility released for UT, so there's every reason to expect it to be worth your time in UT2.
