Installation: Right click on "Source SDK Base 2013 Single Player" then "Properties". Then goto "BETAS" then select "upcoming -" and leave the beta access code blank and click on "CHECK CODE". Then drag "killthemonk" over to the "sourcemods" directory. Oh wait.... If you don't know where that is, it's in your Steam directory. (by default it should be in "C:\Program Files (x86)\Steam\steamapps\sourcemods")
