Actually it isn't the same blue as the Terra Tech Logo Skin, but rather a custom one that was originally aiming to make GSO look like more of a naval corp by changing the color from grey to light blue.
It looks more like the water, even the GSO rudders were painted orange and red to make it more rudder like!
Turned out looking a bit odd, so I am planning on adjusting it to a darker blue and better colors sometime in the future.
How do you get the guns to turn on target?
I've decided not to use the megaton turning trick, but follow ai is hopelessly stupid, and aims for a 45% angle instead of straight on.
Correction: AI does not move at all if enemy is close enough
Correction: follow AI apparently doesn't make the tech target enemies anymore. It makes it follow you. And fire its weapons at any nearby enemies. It does NOT seek out and destroy nearby enemies like it used to.
