Mars Attack is the first Extra Ops introduced in Metal Slug Attack.

Story[]

The story of the event is when the Regular Army has been under attack by Rugname after they have annihilated Dai-Manji into thinking that it is already over. The ending is when Ralf and the rest of the Regular Army has destroyed Rugname, a Mars People can be seen falling into the ground, which later then salutes the Regular Army soldiers. This could possibly imply that the Martians have surrendered, the announcer can be heard saying "Mission Complete!".
