[quote]I've heard that raids will have checkpoints after every boss. What I'm wondering is, when you quit a raid after a checkpoint and then continue it later on, do you have to have the same people you originally did it with? Or can you do it with new people?[/quote] Most games that have a raid mode, have this option. Basically after u kill boss x or z. All mobs leading up to said boss would not respawn. Yes. The same ppl are recquired to continue. You cannot join a raid mid session. As for how these mechanics will work in Destiny. We dont know 100% yet. But all signs point to me being right on this.
