• Car Wrecked | Cause an enemy to die in a vehicle explosion | - | -
• Room to Grow | Upgrade a facility | - | -
• 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
• Bring It Down | Sabotage an alien facility | - | Discover and destroy a Blacksite
• Have a Nice Trip | Cause an enemy to fall to its death | - | Grenading a roof-mounted turret is an instant kill
• Codebreaker | Build the Shadow Chamber | - | Story progression
• A Better Human Being | Recover the Forge item | - | Story progression
• 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
• Mechlord | Hack and take control of a Sectopod | - | Best done after doing the 'autopsy,' as it unlocks the Gremlin MKIII for a better hack score
• A Dark Doorway | Recover the Psi Gate | - | Story Progression

• Shadow Broker | Sell goods worth 1000 supplies to the Black Market (Can span multiple games) | - | The black market will have 3 item types per month that it will buy at a higher price
• The Sun Never Sets | Build a radio relay on every continent | - | The Relays cost more Supplies for every one built globally, while reducing Intel costs to sectors in proximity to it: leapfrogging a good tradeoff, and continents require 1 or 2 Relays to unlock their bonuses.
• Global Resistance | Get all of the continent bonuses available in a single campaign | - | See above
• Brutal Collection | Skulljack each different type of ADVENT soldier(does not have to be in same game) | Captain is story progression, as well as the Codex, which also counts: that leaves the footsoldier, the Sheilder, and the Lancer
• Nick of Time | Evacuate a soldier whose bleed-out timer is still running | - | A purchase in the AWC increases chance of Bleedout vs death
• The Most Dangerous Game | Win a multiplayer match. | - | -
• Defender of Humanity | Overthrow the aliens on Commander difficulty | Commander | -
• Beginner's Luck | Beat a mission in June or later using only Rookies | - | Best done on easier modes

• The Untouchables | Beat the game on Commander+ without losing a soldier | Commander | -
• Immortal Commander | Overthrow the aliens on Legend difficulty | Legend | Practice
• Heavy Metal | Kill an enemy with every heavy weapon in the game(Doesn't have to be in the same game) | Rocket Launcher comes with the EXO suit, rest are Proving Ground projects, with more unlocked once the W.A.R. suit is developed
• The Few and the Proud | Beat the game on Commander+ difficulty without buying a Squad Size upgrade | Commander | Specialists can hack mechanical enemies for a time, and Psions can MC enemies for whole missions, alleviating fire on your own forces
• Overpowered | Beat a mission on Commander+ with a squad composed entirely of soldiers of the same class (but not Rookies) | Commander | -
• Exquisite Timing | Beat the game on Commander+ difficulty by July 1st | You'll pretty much be limited to plot-centric research, and will need as many scientists as possible, and perhaps a laboratory or two: in fact, a Lab should be your first and immediate construction. Not also to unlock the plot, but to rush for unlocking better weapons and armor for the final mission. Second priority is the Shadow Chamber, to discover the location of the Psionic Gate (research the Codex) and the Forge (Research Blacksite vial), as you need to make contact with local resistance to take on these two missions. The penultimate mission, the ADVENT Tower, can be accessed regardless of where it is, as is the final mission. After fighting an enemy type enough (and you have at least one body), some autopsy researches will be instant.
• Who Needs Tygan? | Beat the final mission using only conventional gear | - | Best done on easier modes: save a state on the Avenger before the final mission on your Exquisite Timing run (for less advanced enemies), then redo it with the stater gear on Easy mode.
