6. It has the potential to be a great party game.
I definitely felt like my time with Temple of Osiris was enhanced by the four-player “couch” co-op. I loved experimenting with the characters’ different techniques to solve puzzles, and the game’s level design really encouraged everyone to point out secrets they’ve discovered or to let each other know what they’re about to do.
We also shared a laugh or two at an accidental spike death and the fact that the gods could optionally wield submachine guns.
Nevertheless, if you want to go it alone, single player allows Lara to also wield Horus’ Staff of Osiris, so she’ll have access to every character’s abilities.
