I've decided to wait for the final version before I resume playing the game. And I can say that I'm really looking forward to it. There is one change of the top of my head that I would like you to do. On maps with alien ships many of the aliens tend to stay inside the ship and never go out. I think it would be more fun if once in a while one or two of them would leave the ship just to shake things up a bit. That would make reaction shots more important which I'd like.
I apologize as this is probably not the right place for a suggestion like this one.
