You are a scientist named John Vendetta. You were kidnapped with other Black Mesa personel after The Black Mesa Incident. The kidnappers tried to get from you critical information about the Resonance Cascade and then kill you. Thanks to the HEV suit, it seems like you are the only one who survived and you need to find out who's behind all of this. It's time for REVENGE.
Very basic.. Perhaps add some military camouflage tents somewhere around that place or a crashed Osprey etc.. It looks a little barren. And don't forget bushes & cactus.
I will add both bushes and cactus :)
About Osprey, i think this place is too small for this, beacuse in reality this screenshot is the whole section :O
But im planing live Osprey and Apache and maybe crashed too later in the game.
Also all you actually need to here is break through that grate and go through door which should take not more than 1 minute w/ killing zombie, headcrabs and destroying crates :P
