No Empire Lasts Forever

No Empire Lasts Forever is the fifth and final scenario of Act II: China in Age of Empires III: The Asian Dynasties. The scenario starts out with the cinematic "A New Empire" and revolves around the fleet finding Admiral Jinhai setting himself up as a ruler for natives, the crew find out the bitter truth of Jinhai not being naive as once though and actually plotting against them earlier in India with the Zamorin. Captain Huang, Lao Chen, and the fleet soon get ambushed shortly after by native warriors and are forced to flee into the coast through a series of cave, where they will set up base and counterattack. After the scenario is complete, it will be followed by the cinematic "Sea Change" where the fleet decides to pack up and begin their journey back home in China.

Unlike the previous scenario "A Rescue in the Wilderness", this scenario requires patience, especially at start. The player will have to move from cave to cave unnoticed. Technically they can fight the enemies, but it's better to avoid them whenever possible. When they are forced to fight, they should always use Lao Chen and Huang's special ability to take them out quickly before they cause substantial damage.

Strategy
Players start out on the western edge of the map and are immediately faced with their first primary objective of moving to the norther beaches to recover their crew. They are provided with Lao Chen, Captain Huang, 2 Steppe Riders, 3 Chu Ko Nus, and 2 Qiang Pikemen. Immediately, they should fight and claim the treasure of a hummingbird worth 40 XP guarded by a Cougar as the Treasure Guardian will give minimal damage to the player's units. After the treasure is claimed, the player should cautiously look out for enemy Steppe Riders and other military units patrolling the area and avoid them at all costs, otherwise they will be forced to attack.

Once the coast is clear, a second treasure of a Medicine Man guarded by 4 Cougars will lie, the player can fight off and defeat the Cougars and claim the Medicine Man as he will be beneficial in healing the units later throughout the game. When the treasure is claimed, a small brigade of Changdao Swordsmen and Qiang Pikemen will charge at the player, using Lao Chen's special ability will easily take care of them and defeat them all at once. Once the small brigade is defeated, the player can proceed to further scout further southwest where another cave will lie to their left. Once again another brigade of enemy brigade similar to the last one will charge at the fleet, this time Huang's ability "Heavenly Fire" can be used to take out the brigade swiftly

As the player heads east for the second cave, another treasure guarded by a Cougar will lie, the player can take out the guardian to claim the treasure and will also be rewarded with a Qiang Pikeman as reinforcement. After that the player should allow a an enemy army patrolling the caves to pass by unaware to prevent further causalities, once they left the area the player can proceed to head further Southeast to continue their journey up north to the beaches. As they continue east, they will arrive at a peaceful Aztec native village and a treasure of an Inca Humanica guarded by 2 Outlaw Blowgunners, if any the troops have damage to their health at this point, the Medicine Man should be used to heal them. Once the treasure is claimed the player they can proceed to head east to a long and narrow tunnel. Immediately the tunnel will have 3-4 treasures guarded by Grizzly Bears and a trio of Grizzlies will charge at the player from the caves. Using Huang's special ability will help damage the bears before they are taken down with the fleet troops.

At this point the player will keep exploring further north down the cave where they will face the last treasure guarded by a Grizzly Bear, once the treasure is claimed, the player would have exited the tunnel and arrive onto land by the Treasure Ship where they will reach a friendly settlement, the player will immediately have to configure the Villagers on food by tasking them to hunt Capybaras and Tapirs as well as gathering Berries. At this point, the player should start to spawn numbers of Villagers as well as heading west in the map to take out the enemy Castles and enemy units.

The Castles will be heavily guarded, and it is recommended to put exploration and attacking to halt for a few minutes and moving all military troops back into the friendly settlement, while the army is put on halt, Banner Armies should be trained from the War Academies provided from the settlement and the Ming Army and Territorial Army should be trained to help balance out the player's military. When advancing to the Fortress Age, the Porcelain Tower would be recommended due to the economic benefits for resources the Wonder poses. Once a fair amount of Hand Mortars, Flamethrowers, Steppe Riders, and Arquebusiers are trained. The player will be ready for a full on assault for the remaining enemy encampments.The players should send all their troops to attack the Hill Castles in the west, once they are destroyed the player will take a sharp turn south to reach the enemy Chinese village in the center of the map, over there Admiral Jinhai will lay defending the village and should be taken out first. Once Jinhai is defeated, the player can take out and raze the village Town Center. Any remaining enemy Villagers will quickly garrison inside the Town Center, the Hand Mortars and Flamethrowers will come in handy in quickly razing the Town Center. Once the Town Center is razed, the player can use Lao Chen's special ability to knock out and kill all garrisoned Villagers in one strike.

Now the player can head west to destroy the second and last Town Center, the Town Center will be defended by the last forces of Jinhai, small numbers of Iron Flails and Chu Ko Nus will scramble forward to defend their colony before being defeated, once the second Town Center is destroyed the scenario is completed and the player has officially completed the Act II: China campaign.

The map
The map of the scenario features a slightly different variant of terrain from the previous two, the soil being siltier and brown with trees that will provide a well supply. Networks of cave tunnels will snake throughout the map; twisting and winding in different directions. Silver Mines will be found scattered throughout the map although an occasional Gold Mine may be found exclusively in the cave tunnels, both. Herds of Tapir and Capybara will found foraging the lush greenery of the map. To the north will lie the coast, although there will be no Fish or Whales to gather resources for. Large swathes of land in the south of the map cannot be explored due the cave tunnels
