The grab.

[Farley4Fan]

I've done a lot of testing on the grab bugs in CT,

and found out that you can not grab from right behind, or a little to the left (well, mostly never).

You can grab from almost direct right side of him.

So... From the middle of the back, plus some degrees to the right, until the right side of the merc, you can grab.

Most likely because of the weapon.

Funny, because I can only grab from the left side of the merc and will always elbow if I go from the right side....

I was thinking exactly the same...ahahhaha

Same.  Did you really test it or was that a typo?

Well, i'm pretty sure he means as if he was standing infront of the merc, so his left is our right and his right is our left...you know what I mean.
