Maybe you should do other levels first venture and then get the biolab later (you can pause at the begining and build things) and the biolab really isn't any good. The physics lab is better in my opinion.
I think infected are to make the game more difficult (though i don't know how to beat them when they have a 10x10 square of turrents and a 5x5 ship building area
How about a level editor in which you could choose how many people, where peoples bases are, what building/ships each person can make, place asteroids, etc (mabye include sharing maps)
