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. Two of those are enough to destroy an advanced fusion.

Common counters to Liches are Chainsaws / Eradicators / Screamers / Mercuries - avoid those.
