POWER
 -Build pwr around factories, radars, and shields. Reduces nrg cost.

METAL/MASS
 -Build mass storage around LVL 2/3 mass extractors, increases gain rate.

ORDERS
 -Hold SHIFT to give multiple orders to a unit (eg; build entire base) in a queue.
 -You can move any order in a queue, like adjusting where buildings are placed, etc.
 -Right click on a friendly unit to "assist". Engineers will help others build, etc.

 -Attack Move (order type) is very useful, units will engage anything along their path (Engineers will reclaim mass).
 -Patrol move (order type) is very useful, hold shift and put a few waypoints and selected units will loop the path.
 -Obviously you can set groups with CTRL+#s, useful to group engineers of same tech lvl.
 -Double tapping a group's # will focus the camera on them.
 -Air units have fuel, when it runs out they move about 1/4 the speed. Build Air Staging sites for refueling.

 CTRL+A = Select all AIR units.
 CTRL+L = Select all LAND units (-engineers).
 CTRL+Z = Select all units of currently selected type (eg; If one arty is selected it will select ALL arty units).
 CTRL+K = Self destruct selected unit(s) in 5 seconds. (get rid of old shit fast)
 O = Overcharge (CMDR weapon, requires lot of NRG).
