Dead Air came out on PC yesterday...
Not really too much in changes...
2. Crane = FREEZER DOOR IS GONE!
4. Terminal = You are now forced to go through the Metal detector, which summons an endless horde(?)
5. Finale = Valves big fix was to add fire in that open area. Cute Valve.
Charger and Spitter can completely rape on Dead Air. This map is a perfect example of what level design the new SI were made for.
