Some stuff I keep forgetting to feedback. People might agree or disgree.
1. Chaingun is a bit too easy and good. Can kill dragoon with it in close range combat.
4. Flame thrower is too costly for what you can do with it at the moment.
2. A way to see what classes your teammates are and how many buildpoints are left would be useful.
3. Hydra gas attack is very powerful against non protected marines and useless against protected ones.
5. Killing batle suits giving two frags to aliens might be a good idea.
6. Too much time is spend on building.
1: I think the CG is pretty balanced right now. It costs quite a few credits and doesn't have much ammo. If you charge a CG head on you'll receive 200 bullets. You'll kill nearly anything with 200 bullets. We do need a new sound to make it feel stronger though

4: I like how 4 comes after 1

I agree. Maybe a bit more dmg. Or make the flames reach out further.
2: Maybe some extra scoreboard info?
3: Hydra upgrade costs 2 frags, wouldn't want to make it too strong.
5: Dunno. 2 seems to be quite a lot for the current bsuit. Maybe up the protection a tad first.
6: Aliens can build really fast. only 5 sec timer for killing structures.
