I like this map alot. The gameplay is good.
But this map is probably annoying in realistic mode because of the drop, but the drop is the point of the map so forget I just said that.

I recommend to add some scenery and colliders to that base where the black flag is kept.

That hole in the cliff with all the health and ammo looks like a nice spot to camp, which is a good thing because it's infiltation.

Maybe the building could have been shaded a bit but I really don't care about that because the gameplay is what keeps you playing the map. I could waypoint it but I'm not pro at it... yet.

Good map but more scenery should be..Alpha spawn is in right place.

Well, looks pretty basic, but I think you should smoothen the polys..

Changing the background to a less default setting would be nice, but nonetheless it's a good little large map.
