I will start off by saying that I have only played about a dozen solo games (and haven't won a single one). I started reading through the forums to make sure I was interpreting everything correctly and for the most part I was. Then I started seeing a lot of negativity towards the green marines. i also have read some posts about how to make the game more interesting.
So I am combining the two into a personal mission and that is to not only win my first game but to do it with green marines in the roster. I have played twice so far with this and both times I chose green and grey (another team that gets bad publicity) and then I randomly choose my third team (red both times). I still haven't won but I did make it to the final location in one of the games. I agree that green is a challenge. I am wondering if anyone else has thought to take up the green banner and see if they could secure regular victories with the most ridiculed team in the game? It's not easy being green....
I also want to add that I really like this game!
