Trees/busted cement walls, etc. Not to the full extremity of Assassins Creed climbing, but just a general allowance to scale more than just stairs or hills. I ask, because 1) I'm pretty sure we won't be able to, and 2) It generally isn't a part of the FPS genre -- for whatever reason (and if you'd like to elaborate your thoughts on why that is (Titan Falls wall running/vaulting/etc aside) that'd be cool to hear too). Me: potshooting (potshotting?) from tree tops has always been a gaming fantasy of mine -- arrows from an Elder Scrolls tree (hasn't happened yet) bullets from an FPS/survival game (not yet either).
