Snow End in Sight
Return to Wasp and she warns you of more weather machines threatening Manhattan. Seek out these five weather machines on the rooftops across the city and shut them down before it’s too late.
The first weather machine is located on the small building to the right of Avengers Tower. Brush aside the Frost Giants and then bash the machine until it explodes. You can find the second weather machine a few building tops over with Frost Giants and Security Drones guarding it. Aim at the Drones first with Mjolnir, then sweep through the grounded Frost Giants before wiping out the machine.
The third, fourth, and fifth weather machines are easy flights away. As before, clear the Frost Giants and Security Drones before disabling the machines. After you beat the defenders around the fifth weather machine, Wasp thanks you for your assistance and pledges to work with S.H.I.E.L.D. to figure out how to stop these weather machines permanently.

S.H.I.E.L.D. tech has been devised to counteract the effects of the weather machines, and Nick Fury needs you to protect the heat generator until it comes online. Look for the generator in the park on the other side of Avengers Tower.
You must defend the generator for two minutes. It’s best to have Cap powered up with purple Sparks so that you can use at least one Cap’s Shield Assault during the skirmish. Throw your shield at the Security Drones to knock them out of the sky, and pay close attention to the large Frost Giants, since they do more damage to the heat generator if they strike it.
Be sure to dodge often to avoid damage, and it’s even better if you can drag some of the enemies away from the generator to chase after you. Frost Giants will keep coming; this mission is not about destroying all enemies, it’s about staying alive and destroying select enemies that are going after the generator. After two minutes, the generator sends out a pulse of fire that destroys any remaining enemies and signals victory.
