Got through the Captain campaign but I am unable to win the first Commander mission. I am always bombarded into oblivion, even with three upgraded K-turrets next to each other, which gives them a 30% bonus. Tried lots of turret combinations but I don't manage to survive. Since this is the first mission I am not allowed to send out ships and/or use the super shield yet. Not enough infinium left then to upgrade my ship or turrets further. Anyone managed this?

(As I've stated elsewhere, version 1.0.6 would help as it lowers the difficulty of this level, but it is not available here; only on Steam.)

For the nonexistent posterity (since this game is abandoned and hardly anyone will care anyway):

I've managed now by constructing heavy pulse lasers instead of the basic ones first, as they shoot down most of the stinger ships already in sector 2. If I build basic pulse turrets first, I won't have the money later to build the heavy and super laser turrets needed to complete the level. Have not managed to get all three possible stars yet, but one day I will. Still quite odd that I've managed in later Commander missions to do so.
