Ideas about a tank only map

[Vilespring]

I was thinking about how to make a tank only map. I was wondering what would be the best way to go about doing that.
One of my thoughts was make the tanks have their exit points positioned so they once somebody gets in, they're stuck inside. The tanks would be placed inside a garage with a door only tanks can go through. (Apache Thunder's random collision group, no? ) The map will be littered with repair and ammo stations.

Or you can use a one-sided collision mesh, kind of like the "sidewalk_i" where you can pass through the bottom but not the top.

Also, If you have the players (and bots) spawn inside of the tanks, you can add a death bubble in the middle of the map that kills only foot soldiers and covers the entire map.

but will the death bubble cause injury inside the tank?

What theme will the map be?

Let me know if you'd like a had laying out a height map.

You can also try using a barbed wire fence type of damage on a map-wide scale, but I'm not sure how that will work. I would try the bubble first.

They did it in BF1918. it was a only air map.
