This is based on the concept of minimalism, except it uses more triggers and a very detailed map.
The Spanish have landed in Central America. You, the Aztecs, must drive out the Spanish and keep them from overtaking you. You are in an arena. At one end is your base, with a castle, siege workshop, and barracks. At the other end is the Spanish base, with plenty of soldiers, a tower, and a flag. The object is to bring 4 units to the flag. If your gate gets destroyed, you lose. Seems easy, right?
Wrong. The twist I have added is that you can only have about 4-6 units at a time. Your enemy has an army of 132. Your units, however, can gain an +50 attack bonus for 150 food per unit. You start with 10,000 food, wood, and gold. The food will get replenished for however many kills you make. The gold, however, is limited.
The Spanish have certain superpowered units, such as champions, hand cannoneers, bombard cannons, conquistadors, and cavalry. They have a more numerous army of halberdiers, which are relatively weak, but can do damage in large numbers. Overall, the Aztecs have an uphill climb.
They are limited to the amount of soldiers they can make, but they can produce different combinations of Eagle and Jaguar Warriors, siege weapons, and infantry. Pick the combination that works best for you.
Scattered in the arena are a number of crates. Some may help you, while others harm you. One has food, another has a horse which you can train a rider with. Another has a cart of gunpowder, which you can create a cannon with. Another is a trap, which is explosives that damage your men around it.
There is a pool of drinking water outside the Spanish base. If you bring a wounded soldier to it, you can heal him for 1000 food per 5 HP. Just be careful how much you spend!
There are some hand cannoneers on high ledges waiting to snipe you down. If you sneak up behind them, they won't know you are there, and you can kill them in secret.
Battle for control of your homeland!
