Army of Two 40th Day - You have a choice

Throughout the game at various points you will get asked to make a choice on your actions. Do you let someone live or die? Do you go down one route or the other? These moral choices have some impact on the game, you will only be able to access certain areas if you have made the correct choices. Now I wish I had know about this before then maybe I would not have made the bad choice to get some extra money for upgrading weapons. If you are going to play the game more than once then I suppose you can go through it playing evil & good. But I'm only going to play the game once, I need to finish it off before Halo Reach. Looks like I've missed out on a new weapon then, now I wish I had let that tiger loose in the zoo just to see what would have happened? The achievements are still glitchy on this game with actionabbas missing out on the end of chapter 4 achievement. We might have to go back and do the chapter again because I don't want him to miss out on the end of game achievement.
