# Goal of the game

Survive as long as you can. Raid other towns. Defend your town.


# Advanced tips and tricks

It's best to found new towns far from existing towns, as enemies will become aggressive with town's research.

Are you out of ore patches? Make sure you researched steel processing,
then hand mine a few big rocks to find ore patches under them!

The town market is the heart of your town. If it is destroyed, you lose everything.
So protect it well, repair it whenever possible, and if you can afford, increase its health by purchasing upgrades.

It's possible to automate trading with the town center! How cool is that?!! Try it out.

When building your town, note that you may only build nearby existing structures such as your town market and walls and
any other structure you have placed. Beware that biters and spitters become more aggressive towards towns that are
advanced in research. Their evolution will scale around technology progress in any nearby towns and pollution levels.


# Alliances

Once a town is formed, members may invite other players and teams using a coin. To invite another player, drop a coin
on that player (with the Z key). To accept an invite, offer a coin in return to the member. To leave a town, simply drop coal
on the market. As a member of a town, your respawn point will change to that of the town.

To form any alliance with another town, drop a coin on a member or their market. If they agree they can reciprocate with a
coin offering.
