JR Life was made as a test to see what jrburger95 could do in the source engine and the end result was a simple GMOD clone. It’s not as fancy as GMOD but it’s free so if you don’t want to buy GMOD you could try this if you want.
JR Life was developed by JR Modding Stuff, Released in 2014-04-18
JR Life was Released on Windows
JR Life is a Single Player game
