Subsonic is a semi-recreation of the COD map with the same name and core layout is the same with various changes to make it playable for Red Faction, including new rooms and paths.

Hangar doors can be opened from inside and outside the hangar as well from the intelligence room.
Blast windows located in the Air Tower windows can be opened / closed from both sides, allowing you to close your opponents windows during a battle.
Intelligence room allows access both windows and both hangar doors, as well as a Lockdown mode which will lock down the intelligence room for a few seconds.
One of the shipping docks has a blast door that can be opened and closed only from the inside.
There may or may not be a secret room in the top secret base.
In COD, the base was attacked by a nearby enemy base, hints the destruction.

Fun Fact: The original map is based off King Fahad Air Base in Saudi Arabia from the Gulf War era.

My only minor critique is the planes and hummer textures seem a bit flat and cartoony compared to the rest of the textures. Perhaps even just adding a bit of noise to them might give em a bit more real world grittiness? Also console is reporting that DoorLoop01.wav, DoorEnd06.wav & DoorEnd07.wav are missing. Not sure if those are important or not?
