Complete Age of Empires III Part 21 walkthrough covering the Seminole Map and destroying Beaumont's Town Center. Learn objectives and tips.

Walkthrough
  1. 1
    After the last cache, the explosion destroys nearby trees, allowing your last wagon to pass quicker. Collect any remaining treasure upgrades.
  2. 2
    Head north, back inside the mines. Free the musketeers and send the wagon to one of the camps.
  3. 3
    Save before heading north to the biggest fight yet.
  4. 4
    Of the two treasures, the western one reveals a new objective: FIND AND COLLECT THE SEMINOLE MAP.
  5. 5
    Collect the Seminole map to win this section.
Tips
  • Your army should be large enough to handle the Boneguards in the mines.
  • The final objective is to FIND AND COLLECT THE SEMINOLE MAP.
Walkthrough
  1. 1
    Get the big gun as soon as you start. Build Falconets and towers for defense, and a factory with upgraded peasants for resources.
  2. 2
    Build a base. You will receive a new objective: BUILD TRADING POSTS AT THE NATIVE VILLAGES (500 XP).
  3. 3
    Send Amelia east to build a trading post at the nearest site. Once it's up, you get a new objective: BRING KANYENKE TO THE REVEALED FOREST ALONG THE SOUTHEAST EDGE OF THE SWAMP (300 XP).
  4. 4
    Send your troops east along the cliff north of the nearest treasure ship (where pirates guard a treasure item), then farther east along this cliff to reach the second trading post, avoiding the first red outpost.
  5. 5
    Build a second trading post with Amelia.
  6. 6
    Take everyone south along the cliffs beside the swamp. North of the third trading post, you will find a huge gun on the cliff that comes under your control.
  7. 7
    Knock down any trading post the reds may have built and build your own in its place.
  8. 8
    Send everyone back along the route to the third trading post, as your base will be attacked from the southwest.
  9. 9
    Have ten peasants on farming, ten on lumber, and a few working on the first shipwreck beside the first trading post. Clear any pikemen guarding it and start mining gold.
  10. 10
    Build subsequent buildings northeast of your town center, tucked into the back of the map.
  11. 11
    Send troops southwest to sit on the cliffs directly north of the red base to intercept their fort construction.
  12. 12
    Back at your base, advance to the Industrial Age and choose the Factory card to build a factory. A few falconets and musketeers behind two or three towers are sufficient defense, especially with the big gun active.
  13. 13
    Once the factory is up, upgrade miners to chop lumber or other tasks. Upgrade the factory and market first, then proceed with other upgrades.
  14. 14
    Build one or two more towers on the southwest face of your base for defense.
  15. 15
    Construct a mini-army: a few siege weapons (two rockets from the Home City), about twenty military units (musketeers and dragoons recommended), some falconets (four recommended), and a squadron of sharktooths in the south to protect the cannon.
  16. 16
    Use this army to destroy the red outpost in the northeast of the swamp. The big gun will have destroyed the one in the southeast.
  17. 17
    Take out the outpost beside the red base. Destroy its tower with rockets or mortars while other units protect them.
  18. 18
    A new objective appears: DESTROY BEAUMONT'S TOWN CENTER.
  19. 19
    Send rockets or mortar shells over the walls to destroy the town center quickly. Beaumont will send more units as it takes damage.
  20. 20
    Destroy the medium base behind the walls and kill all units for experience. Be aware of a bug where the level may not end if other buildings are destroyed before the main town center.
Tips
  • The big gun is very tough and can be easily reinforced or defended by upgrading sharktooths from the trading post.
  • The big gun will target the red fort and other buildings within its range.
  • You can send help to the big gun if it comes under attack.
  • Build and upgrade excellent sharktooths from the trading post.
  • The big gun will start hitting the red fort and other buildings within its range.
  • The big gun is doing a great job of eradicating most of Beaumont's armies in the south.
  • A few falconets and musketeers behind two or three towers will suffice for defense.
  • If you can get rid of the base and leave the main town center for last, it might prevent a bug that stops the level from ending.
  • When the town center is heavily damaged, Beaumont will send more units.
