Any good PS4 FPS that I could spend a lot of time singleplayer? I want to be able to get a FPS that I don't need to do multiplayer to get use out of it. Bonus if it has something similar to Halo:Reach's Firefight mode.
No, just main story and side quests, but there’s Regular mode, True Vault Hunter Mode and Ultimate Vault Hunter Mode which ups the difficulty, plus Digistruct Peak but iirc you have to progress in one of the DLCs to get to that
