Halo 2

First-person shooter continuing the fight against the Covenant, an alien alliance bent on wiping out humanity. You play as Master Chief, a super-soldier in powered armor, battling across Earth and massive ring-shaped structures called Halos. The campaign alternates between Chief's missions and those of the Arbiter, a disgraced Covenant Elite, showing both sides of the war. Combat mixes gunplay with melee attacks and grenade throws. You'll commandeer alien vehicles, wield human and Covenant weapons with distinct feels, and face enemies that flank and coordinate. Multiplayer supports online matches across various modes. If you want sci-fi warfare with dual perspectives on a galaxy-spanning conflict, this delivers that structure.
