I did all of these assassinations, my XBOX even says it's at 100%, yet the achievement didn't unlock. Can anyone help? offer any advice on why it hasn't unlocked. It's the same with a few other achievements as well.Posted by E Joshua Miller on 12 Aug 16 at 05:52 Great guides man! Worked like a charmPosted by Jzarp43 on 16 Aug 16 at 01:41 Joshua, the chievo app does that sometimes, it'll unlock randomlyPosted by SolaceConquest on 12 Feb 17 at 20:30 Following the first one and every single time the guy with the drink moves instead of the laptop guy.Posted by SolaceConquest on 12 Feb 17 at 21:19 They must have changed the name in an update as something to chew on doesn't even appear on my challenges. It's probably the one called Mega Byte.Posted by ParadoxReal8 on 07 Sep 18 at 08:42 First challenge is not working for me.
