Please. For the love of God. Do not. I repeat. Do not. Cop out with making the majority of them be multiplayer specific. That would ruin it for me. The campaign is still a ten year old campaign any way you swing it so it needs all the extras and unlockables
it can get to feel fresh. Having said that I'm happy to know you will have to hunt skulls. Reach had nothing to unlock in campaign.
Well, they can't be multiplayer. Or at least as far as I know. CEA's multiplayer is actually Reach's multiplayer. This means that any new multiplayer achievements would technically need to be added to the Reach repertoire, not CEA's. We'll see what happens
@Blade Runner 07 What do you mean Reach had nothing to unlock in campaign? Do you mean stuff like skulls? Because there were the datapads. If you meant achievements, there were quite a number of cheevos in Reach's campaign.
