Fear not Spear, patches are in the works and modders have created some fine changes that help make the game some what playable. Since we have a week or two ahead of you in this game, go to the sticky thread on bugs on this forum. "a" key is known CTD. You will find some others but not much that will keep you from playing the game. I have had my first successful patrol and I'm enjoying the heck out of this game. I have the utmost confidence the developers will clean up the glitches and we move on to wonder mods, etc.
Don't throw in the towel man because it is a very nice game. Read some posts on the forums because when you're in the "know" the game can be awesome!! BTW welcome aboard!
