So now i can play crysis on very high specs - that's cool ^^
But anyway i can't use the TAC-gun.. Does anyone know how to solve this problem?

Thank you

The TAC-Gun is only needed by the last enemy. A very big enemy who comes out of the water and will destroy the warship. Your Friend (Psycho) is flying around the enemy with the Rosenbaum?? woman and she will tell you when you can use the TAC-Gun. YOu have to shoot on the arms of the enemy and in a hole in it.

I know that. This is exacly where i am ^^

HAve you waited till the shields of the enemy are down? The woman tells it to you and you can see it. Then you can aim to the arms and shoot.

I have there no problems.

Yes yes yes ^^
She's telling me all the time that i should shoot...

I found out that this is a common bug...
Maybe you can give me two of your savegames one before the fight and one after it...

Sure, but i think you did´t need them. After the fight the game ends.

I can send you the saves at afternoon. I´m not at home.
