What alien bits should I sell in XCom 2

xcom-2

It would be nice to have an XCom 2 version of the XCom: EU question: What alien bits should I sell?.

It's not obvious which alien corpses or bits of alien tech are safe to sell on the black market. e.g. I know that Faceless Corpses are used to build Mimic Beacons, but are they used for anything else? …If I've built all the mimic beacons I'm going to want to use, should I just sell all the rest of the Faceless Corpses I find?). After I do an autopsy/breakdown of an ADVENT Officer Corpse or Turret ADVENT Wreck, are those safe to sell? etc..

What corpses and other inventory items are necessary to keep around, and what are safe to sell on the Black Market?

Best Answer

You always need 1 corpse for autopsy/breakdown. You also have a minimum number of corpses needed to unlock instant autopsy/breakdown, which means that, if you want to save research time, you will only sell corpses after the autopsy is done. An exhaustive list of other uses for corpses is:

  • ADVENT Trooper: 2 for Hybrid Materials (4 on Legend), 6 for Predator Armor (12 on Legend), 2 per EXO Suit (4 on Legend), 2 per Nanoscale Vest (3 on Legend).
  • ADVENT Stun Lancer: 2 per Spider Suit (3 on Legend).
  • Sectoid: 2 for Advanced Psi Amp (3 on Legend), 1 per Mind Shield (2 on Legend).
  • Faceless: 2 per Mimic Beacon.
  • Viper: 2 for Battlefield Medicine (3 on Legend), 1 per Nanomedkit (2 on Legend).
  • Berserker: 1 per Overdrive Serum (2 on Legend).
  • Chryssalid: 2 per Hellweave.
  • Gatekeeper: 1 for Alien Psi Amp (2 on Legend).
