Oh, and this is a build from January.
A few details anyway: the level was played in medium difficulty mode, with all the HUD features enabled. You must know that "wallhack", crosscom and colored pointers can be disabled. Also, purists should appreciate that it's possible to play with the old-school FPS view, with nothing on screen but the gun reticle.
