Liche is the ultimate weapon of terror and destruction. A heavy aircraft equipped with a tactical nuke launcher.
This guy can decapitate Commanders, destroy Fusion powerplants, or send whole armies into the air with just a single shot.
A well-microed Liche can win you a game, just locate all enemy Commanders and fly over them. Use SET-TARGET to make it not lose momentum when deploying a bomb. Two of those are enough to destroy an advanced fusion.
