Campaign Mission Walkthrough: Part One

The opening missions of Halo introduce you to the core gameplay loop and the immediate threat of the Covenant. In the first mission, "Pillar of Autumn," you will learn the basics of movement, shooting, and grenade usage. The key is to use the environment for cover and conserve your ammunition for the tougher Elites. As you progress to "Halo," the world opens up, and you will get your first taste of vehicular combat. Use the Warthog's speed to your advantage, but be careful not to flip it. For a detailed breakdown of all enemy types you will face, see our enemy types guide.

Mission 1: Pillar of Autumn

• Objective: Escape the crashing ship.
• Tips: Grab a plasma pistol for its charged shot, which is effective against Elite shields.
• Secret: Look for a hidden terminal in the cryo bay for lore.

Mission 2: Halo

• Objective: Reach the control room.
• Tips: Use the sniper rifle to eliminate sentinels from a distance.
• Secret: The "Halo" ring's landscape hides several cave systems with bonus weapons.

Campaign Mission Walkthrough: Part Two

The middle section of the campaign introduces the Flood, a parasitic enemy that changes the game's dynamics. In missions like "The Silent Cartographer" and "Assault on the Control Room," you will need to balance fighting the Covenant and the Flood. For the Flood, shotguns and pistols are highly effective. In "343 Guilty Spark," the atmosphere becomes claustrophobic. Stick to well-lit areas and listen for audio cues. The boss guide provides specific strategies for the Hunter pairs and the final boss encounter.

Key Strategies for Mid-Game Missions

• The Silent Cartographer: Use the beach approach to clear the initial landing zone. The island's interior is a maze; mark your path.
• Assault on the Control Room: This is a long mission. Use the Ghost vehicle to traverse the icy canyons quickly.
• 343 Guilty Spark: Conserve your shotgun ammo. The Flood are numerous but weak.

Multiplayer and Co-op Guide

Halo is renowned for its multiplayer. Our walkthrough covers the basics of the multiplayer mode, including map control, weapon spawns, and team strategies. For co-op, communication is key. We recommend using the co-op guide for specific level coordination. In multiplayer, the key is to control power weapons like the Rocket Launcher and Sniper Rifle. Learn the spawn timers for each map. For a full list of all available weapons and their stats, refer to our weapons guide.

Secrets, Collectibles, and Achievements

Halo is filled with secrets, from hidden skulls that modify gameplay to terminals that expand the lore. Our walkthrough details the location of every collectible in each mission. Finding all skulls is a great way to unlock new challenges and achievements. For a full list of all achievements and how to unlock them, see our achievements guide. The "Halo" ring itself holds many secrets, including a hidden party room in the level "The Maw."

Final Boss and Ending Walkthrough

The final mission, "The Maw," is a race against time. You must destroy the Pillar of Autumn's engines to stop the ring from firing. The final boss is a battle against a powerful Flood form. Use the environment to your advantage and keep moving. After the escape, you will witness the game's ending, which sets up the sequel.
