Defend the Base: Mission 7 - The Covenant (Outskirts of Voi)

This section provides a comprehensive guide for successfully defending the UNSC Forward Operating Base (FOB) during Mission 7, "The Covenant," specifically the intense base defense sequence on the outskirts of Voi. This is a critical juncture where the Covenant attempts to overwhelm UNSC forces before the Ark portal can be secured. Your strategic decisions and combat prowess here are paramount to the mission's success.

Mission Overview & Objectives

• Primary Objective: Defend the UNSC FOB from Covenant assault waves.
• Secondary Objective: Prevent Covenant forces from destroying critical UNSC structures (e.g., communication arrays, supply depots).
• Enemy Factions: Covenant (Brutes, Grunts, Jackals, Elites, Drones, Hunters), with significant vehicle support (Ghosts, Wraiths, Choppers, Prowlers).
• Key Locations: Main Gate, East Flank, West Flank, Central Plaza, Watchtowers.

Recommended Loadout & Equipment

Before the defense begins, ensure you have a versatile loadout. The FOB offers several weapon caches, so prioritize heavy weapons and area-of-effect grenades.

• Primary Weapon: Battle Rifle or Carbine (for precision at range).
• Secondary Weapon: Shotgun or Brute Shot (for close-quarters combat against Brutes and Drones).
• Heavy Weapon (Crucial):
  • Rocket Launcher: Essential for quickly dispatching Wraiths and Choppers. Multiple ammo crates are available.
  • Spartan Laser: Excellent for single-target vehicle destruction, but has a charge-up time.
  • Fuel Rod Cannon: Good for area denial and vehicle damage, especially against Ghosts and Prowlers.
• Grenades:
  • Frag Grenades: Effective against clustered infantry and for flushing enemies out of cover.
  • Plasma Grenades: Ideal for sticking to vehicles and Brutes.
• Equipment:
  • Bubble Shield: Can provide temporary cover in open areas or protect a critical objective.
  • Trip Mine: Useful for setting up traps at choke points or covering flanks.

Phase 1: Initial Assault & Main Gate Defense

The first wave focuses heavily on the main gate, directly in front of your initial spawn point. UNSC Marines will be present, but their survival depends on your leadership.

1. Secure Heavy Weapons: Immediately upon starting this phase, head to the weapon racks near the main gate. Grab a Rocket Launcher and ensure your secondary is a reliable anti-infantry weapon. There are also Spartan Lasers available on the elevated platforms near the main gate.
2. Main Gate Chokepoint: Position yourself on the elevated platforms overlooking the main gate. These offer excellent sightlines and protection.
   • Priority Targets: Brute Chieftains (with Gravity Hammers or Fuel Rod Cannons), Brute Captains, and any Ghosts attempting to push through.
   • Mounted Turrets: use the two mounted Machine Gun Turrets flanking the main gate. These are devastating against Grunts, Jackals, and Drones. Be mindful of their overheating.
   • Vehicle Threat: The first major threat will be a Brute Chopper attempting to ram the gate. Focus Rocket Launcher fire on it immediately.
3. Watch for Flankers: While the main gate is the primary focus, Grunts and Jackals will attempt to flank via the low walls to the left and right of the gate. Use your Battle Rifle or Carbine to pick them off.

Phase 2: East & West Flank Pressure (Wraith Appearance)

As the initial wave subsides, the Covenant will intensify their assault, introducing heavier vehicles and pushing from multiple directions. This is where the defense becomes more complex.

1. Wraith Engagement Strategy:
   • Early Warning: Listen for the distinct hum of a Wraith's plasma mortar. Check your radar for large red blips.
   • Target Prioritization: Wraiths are your absolute highest priority. Their plasma mortars can devastate your Marines and destroy critical base structures quickly.
   • Heavy Weapon Focus: As soon as a Wraith appears (typically from the East or West flanks), immediately switch to your Rocket Launcher or Spartan Laser.
     • Rocket Launcher: Requires 2-3 direct hits to destroy a Wraith. Aim for the top hatch or the rear engine for critical damage.
     • Spartan Laser: A single, fully charged shot can destroy a Wraith. Aim carefully.
   • Repositioning: If a Wraith gets too close to the main gate, fall back to the central plaza or the elevated watchtowers. These provide some cover and allow you to maintain distance.
2. East Flank Defense (Specifics):
   • Covenant forces, including Brutes and often a Prowler, will push from the eastern side of the base, near the communication array.
   • use the elevated watchtower on the eastern side. It provides a good vantage point for sniping infantry and targeting the Prowler with rockets.
   • Be wary of Drones that often swarm this area. A well-placed Frag Grenade or a Shotgun can clear them out.
3. West Flank Defense (Specifics):
   • The western approach often sees more infantry, including Hunters and Elites, pushing towards the supply depot.
   • Hunters are a significant threat. Use Plasma Grenades to stick to their exposed orange flesh, or focus heavy weapon fire on their weak points.
   • The mounted turret on the western watchtower is effective against the infantry waves here.

Phase 3: Sustained Assault & Final Push

The final waves combine all previous threats, often featuring multiple Wraiths and a relentless infantry push. Resource management and tactical repositioning are key.

1. Resource Management:
   • Ammo Caches: Regularly check the weapon caches in the central plaza and near the main gate. Replenish Rocket Launcher and Spartan Laser ammo whenever possible.
   • Health Packs: Several health packs are scattered around the base, particularly near the central structures. Use them judiciously.
2. Central Plaza Stand: If the outer defenses are breached, fall back to the central plaza. This area offers more cover and multiple angles of attack.
   • Chokepoints: The entrances to the central plaza can be excellent chokepoints for grenades and concentrated fire.
   • Marine Support: Marines will often rally here. Use them as a distraction while you focus on high-value targets.
3. Priority Targets (Recap):

   Threat Level	Enemy Type	Recommended Tactic
   Extreme	Wraith	Rocket Launcher / Spartan Laser (2-3 shots / 1 shot)
   High	Brute Chieftain	Headshots with Battle Rifle, Plasma Grenades, Shotgun in close quarters
   High	Hunter	Plasma Grenade to exposed flesh, Rocket Launcher, focus fire on weak points
   Medium	Brute Chopper / Prowler	Rocket Launcher (1-2 shots), concentrated small arms fire
   Medium	Elite (all ranks)	Headshots with Battle Rifle, Plasma Grenades to strip shields
   Low	Grunts, Jackals, Drones	Mounted Turrets, Battle Rifle, Frag Grenades, Shotgun

4. Common Pitfalls:
   • Ignoring Wraiths: Allowing even one Wraith to operate unchecked will quickly lead to mission failure.
   • Overextending: Don't push too far outside the base perimeter, especially when heavy vehicles are present. Stick to cover.
   • Neglecting Flanks: While the main gate is busy, enemies will often sneak around the sides. Keep an eye on your radar.
   • Wasting Heavy Ammo: Save your Rocket Launcher and Spartan Laser shots for vehicles and high-health enemies.

By following these detailed strategies, prioritizing threats, and using the available resources effectively, you will successfully defend the UNSC FOB and allow the Ark portal to be secured, paving the way for the next phase of the campaign.
