the multiplayer pve is a grind. each of the 6 classes have experience levels to unlock perks, and each weapon has experience to unlock weapon perks. see theres a money counter on the right corner you use to unlock hier teir weapons after leveling them up. the single player campaign is pretty good. its a bit short, but its decent, like when games used to be good around when halo 3 came out. but there arent any other games you can play as a space marine so we have to deal with it
