[4PC Variant]: DeadWall

DeadWall means that dead pieces can't be captured.

To emphasize this, they are visually "walled out" (or are they wearing snake skins, Bab?)

I think it's better if they are able to be taken as otherwise they make it difficult or impossible to promote pawns

what happends if you take a peice? does your peice go with it?

You can't take a dead piece in Deadwall. If you are creating a position under DW, there will be bricks around dead pieces.

Be careful when you combine DW and Dead King Walking or/and N-check or/and Koth. It's sometimes a draw in FFA when 2 players are left in my games.
