Ok I can't figure this one out. I clear out an area (outside in the lush environment), and hop into my warthog with a barney, I find entrance to underground so I jump out and go on foot...How the heck do I get my comrad to follow me? I'll kick him out of the hog, but he'll just stand there. I put my flash light right in his face, everything........Am I asking for to much realism? Trust me I'm not complaining one bit, I just want to know if I'm missing something here. Infiltrating an underground covenant fortress alone sucks!!
