Power Stone Mission

Walkthrough: The final Infinity Stone the heroes can obtain without fighting Ultron Sigma himself is found on Knowmoon, a giant space station, no less. On the station is Grandmaster Meio, Strider Hiryu's arch Nemesis. So he and Gamora decide to go fight him and his drones while Mega Man X, Rocket Raccoon, Captain Marvel and Nova go searching for the stone.

As Strider Hiryu and Gamora create a diversion for the other heroes, they are met by Zero who is under the mind control of Ultron Sigma. He'll be stronger than your typical Zombie or Soldier, but defeating him will bring him back to his senses. From there, Captain Marvel and Nova go for the Power Stone at the Core of Knowmoon, but they are stopped by Grandmaster Meio's Drones. You must defeat six of the drones to continue.

Strider and Gamora will then kill Grandmaster Meio together, while Mega Man X, Zero, Rocket Racoon, Captain Marvel and Nova all head to the Core. Once they reach it, they initially taker and secure the Power Stone. However, by doing so, the core of Knowmoon will begin to fall. Inside is a massive load of the Sigma Virus, and now its crashing straight towards Earth.
