They are not using wrist bands to heal the manta in the screen, those are links to hook them up, note that they are riding on hoverboards and the screenshot file name, they are tagging along with the manta holding on via the beams.
As a note, the darkwalker, is a rip off of the war of the worlds tripod, but screw it man, it's the most awesome vehicle I've seen yet in UT, I always wanted to drive a massive relentless laser beam weilding tripod. I can already see the ownage as goliaths are obliterated by beams of fire raining down on them. The only probaly I can see is if the AI targeting system stays the same, as in, any constant firing weapon like the link, or in this case, the lazers of DOOM, has perfect aim and precision, making it essentialy an assured kill for any bot using it, hell you won't be able to win against these things with the old targetting system. So what I'm hoping is that the AI has had an overhall, or I'm going to be straining my 56k to play online which might cause me to make a return in exchange for Crysis or whatever great game is out at the time, but oh well, great thanks to the concept artists who came up with the new vehicles, the modelers who made them and the coders that allowed those giant legs to really walk instead of going through the terrain with the vehicle actualy hovering there.
