I checked out Radioactive Sandbox, and it had the right idea, but the sandbox part was not there.
I was wondering if maybe someone could create a similar game mode except where players can only build with props they find, using a motor tool would require that someone picks up a motor, etc…
Of course, survival is key to the game, so having diseases, bleeding, radioactivity, weapons, all that sorta stuff should be in the game mode.
This would be an awesome game mode. Please PLEASE make it!
