Power Saver Achievement
Avoid disrupting the city's power supply in the On Defense missionThis mission starts with you standing directly in front of Titanium Man. Do your best to dodge and attack when possible. Sooner or later, he'll retreat towards a power generator and restore some of his health. Jarvis will inform you that destroying the generators will make Titanium Man an easier fight, but if you do that, you can't unlock this achievement. Do your best to wear away at as much of his health as possible, in between his recharges, and just be diligent. His health will run after a while.Equip the guided missiles and unload with Y and RT on Titanium Man. He should be almost dead by the first charge. After that keep attack him with those and it wont even matter. This is the whole mission here so just if you die who cares get up and attack some more.
