United Front the 32nd is the two hundred and twenty-first Extra Ops introduced in Metal Slug Attack.
Story[]
Heidern finishes briefing his soldiers, their mission to capture the latest Flying Shelt model being deployed while avoiding its attacks and not destroying it. The Ikaris prepare to move out, with Heidern accompanying them to the battlefield to direct on-site.
On the battlefield, the United Front operation starts against the Invaders. The massive amount of enemy saucers begins to irritate Clark, who wants to destroy some of the enemy equipment. Ralf reminds him of the mission just as Heidern dodges an incoming attack, destroying another saucer. Clark sees that this is acceptable and is tasked with Heidern to distract the enemy, while Ralf and Leona continue the primary objective.
Out at space, Annette becomes irritated by the Ikari's resistance and orders her craft to collect all the United Coins. Back on Earth, Clark wonders if the enemy has a trick up their sleeve. Heidern appears to be oblivious to this, prompting Clark to remind him that they're on a battlefield.
The Ikaris repel the Invader assault. Ralf and Clark wonder if they will get a vacation, as they want to take a short breather. Heidern comes in and allows the team to take a short reprieve before their next operation.
