I have recently gone after the TAC cannon in the armory and I am about to go past the dying general but when I do this the door wont open, the door handle on the other side is blocking my kicks or when pressing T.

If and when I get through the door I can either go a meter to the side where I will fall through the floor and glitch out of the hangar and get stuck on the bottom of the sea, though I wont die it seems that I am still alive and breathing, the power is not decreasing. Or I can continue forward until I get to the flight deck which is completely deserted, not a living soul is found there..

If I choose to not go after the TAC cannon, then I am able to get to the flight deck and attack the four legged alien that shoots a stream ice but otherwise I am stuck..

These three images will show you what happens when I glitch out.

Please is there a fix for this? Any answer is a nice one!
