Mission overview
Keyes returns to Covenant spaces with heavier close-range pressure and less predictable crossfire. The safest approach is to keep a clear exit and avoid fighting every faction at once.
Recommended loadout: A shotgun or automatic weapon paired with plasma or precision fire covers the varied interior fights.
Objective priorities
- Identify the route before committing to lower or enclosed spaces.
- Use enemy-on-enemy combat to conserve ammunition.
- Enter major interior encounters with a close-range answer ready.
Combat and difficulty tips
- Stay near the edge of multi-faction fights until priority targets fall.
- Check dropped weapons after each room rather than carrying an empty favorite.
- Grenades are best used to block pursuit, not thrown into uncertain close-range space.
