After completing all missions related to the Wasted Garage location, enter the Wasted Garage from the fifth floor Radio Tower entrance, and go down to the fourth floor. There are three buttons you must activate. In a room near the staircase to the fifth floor is a red workbench. Crouch down beside it, and press [Interact] to activate the first button. There is no prompt for the buttons, but you will hear a sound from Quake when you activate a button. The second button is in a small room on the third floor. Under a filing cabinet in the corner of the room is the button. It is hard to see, but you can activate it by crouching down and squeezing up against the right wall. The final button is on the second floor, beneath a nightstand drawer and past where you retrieved the Distributor Cap from the vehicle. It can also be activated by crouching down and pressing [Interact]. Once all three buttons have been pressed, go to the dead end stairwell on the second floor, and enter the activated portal near the mattress with the Quake graffiti to reach the secret Quake room. Inside the secret room is the Shambler Plush item, which can be sold for $150.
After you complete the initial game missions and enter wellsprings for the first time you are given the chance to play a couple of different mini-games with the locals. You have to meet with the mayor first and get your own garage and your replacement armor for your ark suit. After you get your armor its time to play. If you don't have any start up money and nothing to sell, look on the mayors desk in his office on the bottom right corner. You will see a vault boy bobblehead worth a whopping $150! Thats even more than you can sell felltrite for! Sell the bobble head and look for an alley where a couple of locals are squatting near a game board with some holograms on it. The game is simple, you get three chances to roll the dice. After each roll the dice will either come up a skull or a crosshair. If you get a crosshair the sheriff hologram in the middle shoots and destroys a mutant hologram. If you take out all of the mutants before the end of the third role than you win, if not, you lose the money you bet. You can bet up to $25 per game. If you get four crosshairs in the first round, you get 10x the money you bet back in winnings. If you beat all the mutants by the second round than you get 4x your winnings, and if you beat all of them by the end of the third round then you break even. As far as I know this game is random, so just keep playing until you win. 041b061a72
