Glad to see new players enjoying DAMP. BTW, if you sent a friend request and you see me online, feel free to jump in.
As I've told many, you're always welcome to my games. It's how I learned from the many who welcomed me when I first
started playing many moons ago
Also, make sure you have installed the 2 "free" multiplayer expansions.
Right Click on the game icon/artwork and select "view game details"
Scroll down, select the 2 multiplayer expansions and install
