Collapse Proof Walls Expanded (CPWE) is a fully compatible sets based and compatible with the original Collapse Proof Wall from Olleus https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=3304639202

This collection contains all the Roofs needed for building of the others collections.
For the moment i can't build nice looking roofs for corners due to missing roofs tiles in the game, i asked the developper if they could add but i don't have a lot of hope.

Other collection also compatible with this one exists:

• CPWE Economy : https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=3584809224
  
• CPWE Base
  
• CPWE Reinforced
