UFO Invader

An enemy from the flight section of Mission 4 of Metal Slug 6.

Standard attack: After an enemy enters its detection range, it fires five bullets in rapid succession and immediately leaves the map. Becomes invincible the moment it starts firing. If all enemy units are destroyed while UFO Invader is still attacking, the remaining bullets will instead target the enemy base and have infinite range.

Costs 120 medals in the shop.

Tactics[]

UFO Invader's strength lies in the late game, where it becomes a source of simple, spammable damage. In the early and mid game, it is very expensive to summon for a moderately-damaging hit-and-run unit and should only be used in very specific situations. It is however one of the few early units that can hit an attacking Slug Armor at the base without risking knockback, dealing an easy 2k+ damage.
