(The game takes a couple of minutes to load, but it's well worth it)
I'll give you a few tips but it's pretty straight forward. Click in the squares to build buildings. You need to put people to work in your factorys so make sure you build houses. Then in the bottom left, add the people to the factorys. Buy ammo and click on the attacking enamies to kill them. Once you build a building click on it to upgrade it to the next level. You can also build ditches for military units. When you have military units, click on a outpost to add units to it. Good luck and have fun!
Sim City goes to war, Well not really but this flash game is as close to that as your going to get. Build up your factories, houses, upgrade, train troops from barracks, build towers and defend against enemies.
