To the people who complain about balance,
Try playing with a different number of people, because balance is NOT the same. There are graphs out there of this.
The teams are just so different that it's hard to tell really. Most games come down to play skill and teamwork.
You can have a team of average players, and through teamwork, defeat the team of one insane player + noobs.
An example of this was one match on atcs the other day, s3 aliens vs s2 humans. The alien downfall was their bad builder making a base inside the box outside, and not coordinating their attacks. I snuck out of the base with a rifle, killed some dretchs, shot 2 acid tubes, died, bought prifle + nade, went back and killed both there eggs, while my teammates distracted the tyrants in the hallway. Shortly after that, we won!
