Complete walkthrough for Part 20 of Age of Empires III, covering objectives, strategies, and tips for defeating the Mexican army and Boneguard forces.

Walkthrough
  1. 1
    Defend your fort against waves of Mexican units using siege weapons positioned on the walls. Keep field guns and rockets at each corner.
  2. 2
    Use a priest to heal damaged siege weapons, which is more cost-effective than replacing them.
  3. 3
    Send a peasant to rebuild destroyed wall sections or repair standing ones.
  4. 4
    Keep an eye on wall health and ensure gates are not destroyed.
  5. 5
    When Cooper appears with reinforcements upon the timer's run, a new objective is issued: DESTROY ALL THE MEXICAN ARMY'S TOWN CENTERS.
  6. 6
    Send your army to the north-west base and destroy all buildings, prioritizing the Town Center with mortars while soldiers defend against enemy peasants.
  7. 7
    The south-east base has two Town Centers. Repeat the strategy: wait for an attack, then send your army to destroy them.
  8. 8
    The level is won upon the destruction of the third Town Center.
  9. 9
    For the Home City Level 21, you receive 258,772 XP and the CATHEDRAL - EXTENSIVE FORTIFICATIONS card.
  10. 10
    3.3.3 THE BONEGUARD'S LAIR: Amelia follows Beaumont to his gold claim where a surprise and an old friend await.
  11. 11
    Primary Objective: FIND BEAUMONT. This is an RPG-ish mission.
  12. 12
    Go east from the starting point until you find another cave entrance where Beaumont is with two Boneguard units.
  13. 13
    Objective: DRIVE BEAUMONT AND HIS MEN OUT OF THE MINES.
  14. 14
    Kill the two Boneguards and head west for another objective.
  15. 15
    When fighting Boneguards, send your unkillable Heroes in first to draw their fire to avoid losing soldiers, except in the final fight.
  16. 16
    Secondary Objective: DESTROY THE WEAPONS CACHES (500 XP).
  17. 17
    Destroy a weapons cache, kill two Boneguards to the north-west, take down a stockade for three free units, kill two more Boneguards to the north, and send a wagon back to Kanyenke's camp for reinforcements.
  18. 18
    Along the southern pass, there are three camps: the western one provides five Cree trackers per wagon, the northern one provides five clubmen, and the eastern one provides two medicine men.
  19. 19
    You only need two healers; distribute the remaining wagons between the tracker and clubman camps.
  20. 20
    Bring Kanyenke up to join your forces. Send your Cree trackers into the mines, then head west for more enemies, another wagon, and a stockade north of the first mine entrance.
  21. 21
    Send this wagon to a camp for more units, then head north once your new units arrive.
  22. 22
    North of this location, you will find another weapons cache and more enemies, followed by another wagon.
  23. 23
    Caches are guarded by wolves.
  24. 24
    There is another weapons cache to the east, along with two Boneguard pistols that boost hitpoints by 30% (give these to Amelia).
  25. 25
    Go east to meet Beaumont, then east and south for Boneguard armor (consider leaving this for later) and clubmen in a prison cell.
  26. 26
    Head south to where you first met Beaumont, then north-east into the next part of the mines.
  27. 27
    Up here, find another guarded wagon. North of this are Boneguard muskets (leave them for later), another wagon, and the Eye of Ornlu (worth 200 XP).
  28. 28
    Split your troops into three groups: healers, Cree trackers, and everyone else. Wait for your wagons' units to reach you before proceeding.
  29. 29
    To the east, find another wagon and imprisoned skirmishers. South of here is the mine's exit and another cache beyond it.
