Infantry and Cliffs

[Gobalopper]

I was checking out the old interview with Lewis Peterson at GAMECENTER. During it he mentions that there will be certain areas of the cliff wall that only infantry can get through, I had not heard of this before and sounds like an interesting tactic if used right, you can check it out here, the infantry part is at about the 10:20 point. Looks like they are trying to make the infantry units more worthwhile longer unlike other games where after the first few missions they are worthless.
