F.E.A.R. 3

This can be done either Single Player or Co-op

You can quit out after you get a save.

You have to make 100 Psychic Links where you either share or steal the body. Sharing the body provides you and your friend 1000 points each where stealing give only one of you 1500 points.

Stealing the body and sharing the body both count towards the 100. You can alternate between the two as much as you want. But it only counts towards the 100 if you are the one making Psychic links. If your friend makes one it doesn't count towards your 100.

First of all, this is for doing a Psychic Links with bodies scattered throughout the game. These are the bodies that have an aura around them and you have to press and hold "X" when your close to them to do a "Psychic Link."

The achievement description is misleading because it implies that this has to be done in Co-Op with another player because that's when you get the option to "Share" or "Steal" the Psychic Link. "Sharing" gives each players lower amount of points while "Stealing" gives the player who is performing the Link the full 1,500 points. If doing in Co-Op, be aware that only the Psychic Links YOU personally initiate (you're the one who presses "X" next to the body and makes the choice to "Share" or "Steal") count.

However, if you're playing solo, all the bodies you discover and Link with count towards the achievement. This achievement popped for me towards the end of Interval 07 in single player before I even played co-op. So it's actually possible to get the achievement before even beating the game your first time through on solo...just make sure to explore the environment thoroughly to link with every body you find.
