So save your game BEFORE you move into range, and that way, if you fail the stun, you can reload and try again. If you fail that crucial first stun, you will be right next to the alien and get shot in the face. Yes, I have missed a stun at 90% once or twice, so that leads to my next tip.įourth, SAVE BEFORE YOU MOVE INTO STUN RANGE.

It only does up to 2 damage, so won't kill the Outsider and it's reduced health will make the stun attempt easier (The stun starts out at a 70% chance if the enemy has 3 health, 80% if they have 2 health, and 90% if they have 1 health).

Thirdly, if you can, shoot them once with an unmodified pistol. Because of this, DO NOT OVERWATCH! You don't want the creature moving and then getting shot down while you are trying to manuever your arcthrower soldier into range. Second, these guys only have 3 health bars, so almost every weapon will kill them in one hit. I have never seen them in any other missions, only ones where you fight in and around spaceships. These aliens are only found on spaceships that either crash landed or set down. However, here are a few tips to make this achievement easier.įirst, an Outsider is a crystal alien that when first met, is a glowing pink/orange/reddish crystal and then it morphs into a humanoid during it's cutscene.

How to Earn: This achievement is story related and can't be missed.
