The UAV was part of the whole crosscom thing. You control the UAV and other vehicles, see stuff from the perspective of your team mates, locate enemies and even keep tabs on their health level, and whatnot. GRAW was all about that, to the point where it felt more like a clunky RTS than a shooter, least of all one of the GR sort. Combined with the air support thing, there wasn't much of a "ghost" feel to any of it.
I can deal with the techno stuff, but I was hoping that it'd be reigned in a bit and made into auxiliary features as opposed to main attractions and gameplay tools.
