After you have defeated quark, go back to where you found him and look for a tower jutting off the runway in front of you, thenrun to it. the gold vendor is at the top of the tower, where you can buy the gold versions of the bomb glove, glove of doom, pyrociter, suck cannon, and like one or two others. how to get to the top you might ask? sniper veiw up near the middle, it will look like a glass shaft. go to the bottom of the tower. then stop at the entrance to a hallway thru it. wall jupp up whe walls at the very edge then pull yourself up, next you step on the elevator button which will take you to the vendor up the tube you saw eirlier. Keep in mind that you need gold bolts and regular bolts to buy the gold weapons at the vender. pay the vendor its bolts and walla!
