03 Halo: The Master Chief Collection
Still one of the best. We don’t need to tell you what happens in Halo, so instead we’ll just note that this is a complete tour of the series’ split-screen golden years. The shooting is great, but the star of co-op might be the vehicles. There’s nothing like jumping in the turret of your mate’s Warthog. Once Reach is added later this year, TheMasterChief Collection will offer six of the greatest co-op campaigns in gaming.
