so i actually brought crysis and was having a great time powering through on the easy setting as i do all games first play through. i notice a few bugs along the way but the most annoying is the TAC cannon on the final boss. i installed the 1.2 patch for crysis but no matter what i do i cant get a taget lock to fire down the gaping hole you open up in its belly. all 4 turrets have been destroyed. both arms destroyed both turrets on either side of the hole you blow open destroyed. i dont know if anyone ever found a solid fix for this? its highly annoying as i want to "officaily" complete the game. some threads recomend lowering GPU settings, which i have done. some threads recomend replaying the whole level, which i rather not do some threads recomend replaying from an earlier save. which i've tried. some threads recomend not using the TAC cannon except for that last hole. tried that one too. just cant get it to find a lock. running windows 7 64 bit.
