Ok, tried it. Brace yourself for the feedback.
First of all, the boring stuffs, some bugs. I can't start the mission with the Space Hulk, actually the mission briefing don't even show.

Now for something more interesting.
The imperial navy is overpowered for now as they tend to wreck everything in the campaign. I made a fleet of 2 Falchion and 2 Cobra and butchered pretty much everything that fly without adding anything on them. I think the problem is their extremely high stats, nearly capital ship level. Hell, they got more armor than an Onslaught! Also for some reasons, the Cobra AI never use their torpedoes.
The fighter wings are surprisingly ineffective. Because of their stats they are great against big slow ships but are useless against fighters as they just can't aim, probably because of their very narrow firing arc. Also might need to balance the Thunderbolts. For now they are pretty much better in every way to the Fury which is weird as the Fury is supposed to be the very best interceptor of the Navy and the Thunderbolt is quite outdated.
For the weapons. The gun batteries should have a higher fire rate (something like an auto cannon) and generate less flux, decreasing the damage would be better too. On the opposite, lances are weapons than put a strain on ships generator and as such, should generate a lot of flux, and very high damage.
I'll try to look more in depth in the ships stats as soon as i can.
The music fit well indeed, what is their names?
Also for the copyright stuff. You should put trademarks and logos are the property of their respective owners and yada yada... Just in case, to avoid you trouble with GW (a 40K mod for Unreal Tournament got some problems for forgetting that).
Whinging not quite done yet. I'll come back annoy you as soon a i can.
