Halo 5: Guardians

For the first time in series history, the 2015 sequel shipped without split-screen co-op, removing a staple feature. Its REQ Pack loot boxes tainted an otherwise solid multiplayer, while the story averaged a 74 on Metacritic—30% lower than Halo 2's 96. The game's misguided focus on squad mechanics and microtransactions left fans longing for the linear campaign of Command & Conquer 4's base-building ruin.
