From brubinow, "In the demo I saw, the SouthPeak demonstrator gave his soldier a sniper rifle and a repair kit. He then sequestered himself atop a hill, built a turret, and let the kills roll in. In addition to the different combinations of weapons, you can assign attribute points to your soldier to change things like armor and weapon damage.
New combat objectives can appear in reaction to player performance. For example, a particularly well-performing player of the opposite team may be tagged as a VIP, so killing him would be worth extra points."
