Yep, skill trees. One is for the Rage mode, something I didn't get a chance to use in the demo, but most of the skill tree seemed to allow longer use or additional bonuses for using Rage mode.There was a Combat skill tree where you could unlock the ability to do additional damage (initially with knives but depending on what you choose later, it looks like you can build towards specific weapons), Finally, there was a Survival skill tree which dealt with how much health packs worked and how much damage you could take.
