Actually had fun on that Spec Ops mission where you attack the Fuel Depot, running through the forests with NVG's was pretty cool, same with the mission after that where the regular marines assault it. So far hating the mission where you have to extract the POW's, dudes keep dieing.
Question, how do you use grenade launcher?
I have the Mk16 Assault one, with the under barrel GL, and it says press the ' key to switch ammo type, I do, and select HE Grenades, and it switches my weapon to Knife and disables my mouse pointer and mouse wheel so I have to restart the game.
