Help! I'm playing War for Cybertron on the X-box 360 and I'm stuck. In chapter 8, in the Autobot campaign, I can't seem to get past the part where you have to fight off Decepticon snipers and keep Ratchet alive long enough so he can repair Omega Supreme completely. I've tried grabbing the turret or using it while stationary, I've tried the healing grenades, I've tried staying near Ratchet and ducking into cover when needed, but I always either get overwhelmed by sniper or aerial fire or Ratchet gets killed. Does anyone have any suggestions? I'm real sick of this stage and would like to move on. Which character should I play it with -- Optimus, Warpath, or Ironhide? I also find myself getting motion-sick a lot -- I'm playing the game on a widescreen HDTV and get dizzy after playing a while. Never had that happen before, though I also get it now when I try to play Batman:Arkham Asylum too. Anyway, any advice would be appreciated. Thanks in advance.
