Terra Alloy is a much stronger version of the Matrix Enhancer upgrade. For most units which feature this upgrade, such as the Aegis Barrier or Defensive Wall, this upgrade can provide a very dramatic increase in the maximum HP for a unit. Terra Alloy is more expensive than Matrix Enhancer but tends to be far more useful because it's found on units meant for shielding your base.
