Forge Canvas for Breakout

So there are 3 forge canvas for Halo 5. Would breakout be in Space, is it a forge canvas that hasn’t been announced, or is it just a basic arena map?

In the post is says all Arena/Breakout maps are forgeable. So i’m assuming it has its own canvas.

EDIT: They also said every item is placeable on ever map, so maybe theres different categories of objects. Such as the big icy rocks, or the blue grid breakout pieces.

The thing is I watched some of my old beta clips and the Breakout maps had a space background, it is quite possible that the breakout maps where made entirely in forge but cleverly hidden with extras to make you not think of it that way.

Pretty sure the Breakout maps are forged on Space.

Definitley made in the space canvas
