Theres the second time this bug happen. The first time I un-installed the game, re-installed it and this bug happened at the same place the first time it shows up.
It happen a short time after the helicopter shootout on the deck of the ship. I saved my game and quit playing the game. This bug happened when I reloaded my saved game. I can walk through wall, and also can move up as if there were no gravity.
Quitting the game, reloading an old save didn't do anything. I can still walk through wall.
There is no more fun to this game at this point! I would like to finish this game but I can't do it no more!
Please do something for my issue or at least send me another different game because it's very frustrating buying a game and feeling that game isn't properly finished...
