World of Padman on Linux Mint

Freeware FPS shooter running on a free OS.

If you have trouble getting it to run just search for the executable it'll run from anywhere on your system. Although you should move it to a program specific directory, like usr/share/bin.

/usr/share/worldofpadman-1-6-2/wop-/linux.x86_64

Just run the executable in your terminal. It'll run on Windows and Mac OS as well but I haven't really used Windows in a while.

It's a Reskinned Quake 3 done by a German artist that goes by Ente.
