We're making Worms Armageddon maps! Make yours using the following information:

1) Your map must be a PNG image.
2) Minimum image size is 640x32
3) Maximum image size is 28408x30552px for island maps and 32512x32600 for cave maps.
4) IMPORTANT: Both X and Y values MUST be divisible by 8.
5) ALSO IMPORTANT: Use up to 64 colors in your map, and ensure you use pitch black (#000000) for transparent parts. Worms Armageddon will not read transparent PNGs. If you go above the limit we will need to convert it to 64 colors, which will make it look bad!
6) The default size for a Worms map is 1920x696. Anything between this and twice as much is playable. If you make something bigger or smaller, make sure you know what you're doing!
7) Worms' hitboxes are 9x16 in size, with the following shape:

Your map does not need to be playtested, so you can try to make one even if you don't have the game! We can still try to play it.
