You can set formations and give orders such as what range to fire at, as well as target specific turrets or subsystems. (where you click on a ship determines where shots are aimed) What components your ships have, *heavilly* effect combat: i.e. lasers and missiles with the firecontrol command module are very deadly at range while mass drivers and the hammerhead command section are good for close range fighting. Firecontrol and spinal mount beams act like Homeworld's ICFs. Mix those with some point defence ships and plasma torpedo frigates and you have a good force.
Overall you have about the same depth of commands as you have in Homeworld or Nexus. The main difference, and why I like this, is that it adds in a lot of the strategic depth of Master of Orion.
But definately the demo is limited due to having so few techs, and only destroyer ships. But still very fun for multiplayer.
