XCOM: Enemy Unknown

XCOM: Enemy Unknown Achievements

As A Scalpel

Earn the "Excellent" rating in every performance category on a terror mission.   

This can be done on any ‘Terror’ mission. The following are the 3 categories and requirements for an ‘excellent’ rating:

- Aliens killed: Kill all aliens on the map
- Operative lost: No squad members can be killed
- Civilians rescued: At least 75% rescued.

The hardest part of this achievement will be rescuing civilians, as the aliens will not waste any time killing them. Unlike some other missions, you will need to play offensively, taking the fight to the aliens quickly. Try and focus most of your attention on killing aliens, instead of rescuing civilians as you can always double back or use a weaker squad member to rescue them later. When engaging aliens, particularly Chryssalids, make sure you focus all your fire on one and kill it, before moving on to the next. In Terror missions, having three wounded aliens is much more dangerous than one enemy at full health.

As long as you have received a rating of ‘excellent’ in all 3 categories, the achievement will unlock during the mission results screen.

TIP: Outfit your squad with ‘assault’ and ‘heavy’ classes as these are better suited to close quarter combat, and (your assault soldiers) can utilise the ‘Run and Gun’ perk. Also to make this achievement easier, outfit a squad using your most experienced soldiers.

I got this achievement by moving quickly and killing the aliens as soon as I could. If you don't allow them to kill the civilians they will count towards the saved column at the end of the mission. I got an excellent for all 3 rating (kills, no squad deaths, & 14/18 civilians saved). So don't be alarmed if one or two civilians die as long as you get the majority.

Little luck always helps on this one too. My advice, take out chrysalids as soon as you see them otherwise you might get swamped with zombies and unltimately even more chrysalids.

Also, it may be good to bring a plasma sniper with archangel and the In The Zone skill. Chryssalids can't go in cover so, the plasma sniper can basically one shot them all. Drones as well. The only bad thing is if the enemies all stay in buildings.

This is way easier to do later on in the game once your crew is pimped out. Have everyone using all Plasma weapons, and have multiple snipers (or assault). Just go full offensive and you'll get it quick.

All aliens killed
No operatives lost
Minimum 14 of 18 saved

Two groups of floaters and one group of chrysalids all bunched together for a group photo (rocket).
From the last group two chrysalids charged my squad and only one went for the civilian. Got that one with another rocket by guessing where it was.
