Idea for fixed width maps

[helltone]

Can we have them infinite on one direction only? currently you can have them infinite on two directions (fixed width or height). I mean a U shaped map would be cool to play in so you can defend on one side only but always have to push the aliens back before expanding. Shouldn't be hard to implement since they already have the two direction infinite map option.

This is easily doable with the map editor.

Have you tried leaving only one direction empty?
