For Destiny PS3 owners, do we HAVE to have playstation plus to play the other game modes or is that for ps4 users only? I am not sure if this has been asked already, but I was told by my brothers friend that you need playstation plus to play in the crucible, for example, and that's for both ps3 and ps4. I understand the ps4, but the ps3? Doesn't add up. If anyone has knowledge on this, that would be great. Thanks!
