Walkthrough: All of the heroes have now been exposed to the Sigma Virus. The clock is ticking; it's only a matter of time before Ultron Sigma will be able to control them too. The need all the Infinity Stones they can get their hands on, and they need a way to somehow harness their energy. Dante is sent to slay Jedah, while Thanos takes a small group to Abel City in order to access a Lab that can create a weapon out of the Infinity Stones. The remaining heroes agree to go to Xgard, where our story began, to face Ultron Sigma. The goal isn't to defeat him, but rather hold him off long enough until the weapon can be made and Dante to retrieve the Soul Stone.
In Xgard, Ultron Sigma sends three Xgardians and three Ultron Drones fro Chun-Li and Nova to fight. After Chun-Li and Nova defeats all of these foes, Mega Man X and Rocket Raccoon must destroy two more Ultron Drones. After their victory, Mega Man X contemplates falling back from the barrage, but Rocket Raccoon reminds them that this is the final Mission. Two more Drones come, this time for Chris Redfield and Captain America to battle. After they are successful, Hulk and Haggar must fight and defeat one last Xgardian and Ultron Drone.
