• Heroes of the Resistance | Beat a Retaliation mission with less than 3 civilian deaths | - | Easier modes reduces enemy chance-to-hit and damage: unlike EU/EW, enemies will more prioritize attacking XCOM soldiers once a pod is activated. So, this may require rushing to engage as much as possible, putting your soldiers at risk. Given that it takes about 3-4 turns to cross a Retaliation map, and you're only allowed two civvie deaths: the moment you see a MISS! during Alien Activity, that is your cue to rush to get this achievement. Keep on top of your save states, as well.
• Cyberlord | Earn a second tier hack reward | - | The locked doors and containers of certain mission objectives, and the 'light poles' in cities have lower hack scores than, say, a Sectopod

• A God Falls | Kill an Avatar | - | Story progression
• Stop Hitting Yourself | Kill an enemy with a hacked turret | - | -
• Now Am I Become Death | Kill 3 enemies in a single turn, with a single soldier, without explosives | - | Ranger's Reaper, Sharpshooter's Standoff, Specialist's Capacitor Discharge, and the Demo can use any of the 'special effect' grenades (acid, poison, fire), as long as the effect does the kill during Alien Activity
• Meat Over Metal | Kill a Sectopod on the same turn you encounter it | - | Focused fire works. Also, luck of the draw with a gun equipped with a Repeater upgrade
