CEA/Reach achievements????

Is anyone else having any difficulty getting the achievements i.e armor lock and infection ones? Are they map specific? Anyone have an idea?

I’m pretty sure you have to be playing an Anniversary map for the Achievements. It’s wierd considering I bought the Noble and Defiant Map packs and got 1 or 2 of the Achievements on the normal Reach maps.

yeah i know. its weird

I haven’t asked or seen anyone address it, but does it matter what disc you’re playing from? THe achievements are for Reach, so while you can play the multiplayer from Anniversary, do you need to be in Reach to unlock them?

CEA multiplayer is reach’s multiplayer, I believe you can play it on reach if you use the DLC anniversary map pack code, if you do not have that code you can play it from the disk.
