I'm on the very last boss of the game. And I'm having a difficult time. Since those little buggers keep respawning on me, I have no chance other than running the entire time. You have but a split second to line up your shot. I must of taken 8 Missile Lanuchers used all the ammo from them and the hatch STILL will not open to me to nuke. I think I'm hitting the correct place. It's the shiny blue area. I might have a bugged loading like from before but who knows... *sigh*

Does anyone know how to use the damn Tac gun? I'm on the aircraft shooting a bunch of aliens, and I can't use the damn gun. All I see on the bottom right is the symbol for infinite. I'm battling that really huge guy.
