Undead Sharpshooter Rank 4

[IC3 L3G3ND]

My bad on the last thread.

Right i'm a little confused on this one.

It says kill 1 of each of the 4 undead types in 1 Dead Eye Meter.

I have got all 4 of them and done it.

I've tried it with them hogtied and it just wont unlock.

Me and a freind have both been struggling for 3hrs now to get this one.

Anyone have any suggestion as to what to do or how you did it?

I did it right outside the south gates of the El Presidio fort. Every zombie type spawns there. Just stand on one of the cannon towers.

still having no luck, thing is im getting all 4.

Fat zombie who charges
Normal zombie
Spitting zombie
Zombie on all fours who runs real fast

This is right isn't it?
