"New Alien Invasion!
They attack from the skies with their ring lasers."
VFO

The UFO Invader is a playable unit in Metal Slug Attack first appearing in the Extra Ops titled "Alien vs. Morden". Parts and items are currently available in the Another Story SP's first chapter.

It is similar to the Mini U.F.O., but is much stronger. It is useful among high-leveled players when it has unlocked MSA Skill small + 4, it leaves the battlefield, giving AP to the user in the process. When maxed out at level 50, the player will obtain 200 AP (provided that it doesn't get destroyed), netting a gain of 120-132 AP for each UFO Invader that successfully leaves the battlefield.

The UFO Invader can be compared to its Ptolemaic counterpart, The Flying Tara Ver. P.M. As both units have the same purposes (AP Recover), however their main difference is that UFO Invader deals much damage in its attacks at the cost of slower speed, while the Flying Tara Ver. P.M. is faster but deals less damage.

In addition to this recovery, it also provides an health buff for ground Invaders and attack buff for Flying Invaders, though the primary usage of this UFO is for AP recovery.

When placed in a deck with the Invader, Winged Invader and the Flying Parasite, they form the "Aliens" team, lowering their AP costs by 20%.
