Anyway, here's the last update on this side project. I'll only come back to it after I'm done with ctf_aerospace or I may not complete any of them.
The idea is that the Blue team has a base on the mountains and is constructing a giant laser to melt the ice on the top of the mountains and flood the red team's base.
In response, the red team manufactures a tree-sawing tank and storm into the mountain to destroy the blue team's giant laser!
Level design-wise, the great challenge I'm going to have is that I have rotated the cave area by 45º to add a nice variation of shapes to the base. The inner base itself will be aligned to the hammer grid, but the cave and ouside areas will be rotated.
