Putting the headset on will bring the player to a virtual reality store named "Steme", which sells copies of Postal Redux, and parody versions of popular steam games. (including Counter Strike: Global Offensive and Doom) The cashier will also give the player tips from the future, like betting on the Red Sox and not buying Postal 3. A Sports Almanac can also be seen outside the store, as a reference to Back To The Future.
