# 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.
    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.
- How to get more ores? Make sure you researched steel processing,
    then hand mine a few big rocks to find ore patches under them!
- How to get more oil? Kill worms - some of them will leave you an oil patch
- 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 increase its health by purchasing upgrades.
- It's possible to automate trading with the town center! How cool is that?!! Try it out.
    Tip: use filter inserters with to get coins/iron/.. out of the market
- Fishes procreate near towns. The more fishes, the quicker they multiply. Automated fish farm, anyone?
- Use /rename-town NEWNAME (chat command) to rename your town

# Town members and 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.
- 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.]]
