Symmetry makes for fair maps

Each player should have at least 1 Base and access to Resources
Walls create chokepoints and tactical depth

How to Submit a Map

There are two ways to contribute map designs to the MicroRTS competition:

Option 1: Use the Editor (Recommended)

Switch to the Map Editor tab and design your map
Click Export XML to generate the map file
Click Download .xml to save the file
Fork the MicroRTS repository
Add your map file to maps/<WxH>/YourMapName.xml
Open a Pull Request with a description of your map design

Option 2: Write XML Manually

Map files are XML with this structure:

<rts.PhysicalGameState width="8" height="8">
  <terrain>0000000000000000000000000000000000000000000000000000000000000000</terrain>
  <players>
    <rts.Player ID="0" resources="5"></rts.Player>
    <rts.Player ID="1" resources="5"></rts.Player>
  </players>
  <units>
    <rts.units.Unit type="Resource" ID="0" player="-1" x="0" y="0" resources="20" hitpoints="1"></rts.units.Unit>
    <rts.units.Unit type="Base" ID="1" player="0" x="2" y="1" resources="0" hitpoints="10"></rts.units.Unit>
    <rts.units.Unit type="Worker" ID="2" player="0" x="1" y="1" resources="0" hitpoints="1"></rts.units.Unit>
  </units>
</rts.PhysicalGameState>

Terrain Values

0 = open ground
1 = wall (impassable)

Map Design Guidelines

Maps should be symmetric for fair play (rotational or mirror symmetry)
Common sizes: 8x8, 12x12, 16x16, 24x24, 32x32
Each player needs at least one Base and access to Resource nodes
Resource nodes are neutral (player="-1") with resources="20" typically
Consider chokepoints, open areas, and resource placement for strategic variety
The competition uses maps/8x8/basesWorkers8x8.xml by default
