I've used the search function on the forums already. Where could I find a Foundry canvassed map with the two base sides walled off? Walled off like Onslaught and Amplified Muchas Gracias
Have a go at making one. This way you can be smart with object placement so that you don't run out of objects to use on your map. Also no one has made a canvas like that. The closest, as ben said would be a grifball map.
