Defensive Matrix.
Cost: 100 Energy
Range: 10
Used by the Science Vessel. Creates a 250 Hit Point non-regenerating shield around the target unit. After about 60 seconds, the effect wears off even if the shields haven't run out of Hit Points. Note that there is some damage that can "leak" through the Defensive Matrix, causing a unit to take a couple points of incidental damage. Cloaked units surrounded by a D-Matrix are automatically detected by any enemy units, but the extra 250 HP are usually worth it. Using D-Matrix more than once on a unit will replace any old Matrix with the new one-- you can't "stack" D-Matrices.
