Because Arcadia is going to close soon, I'm giving away the map secret since ya'll gave me important feedback. Launching the Rocket: Go into the teleporter room (lab) and press the keyboard on the right Go into the headcrab room and press the panel which is glowing blue Break all 8 cameras. There are 4 upstairs, 4 downstairs. Go into the mine and activate the drill button. Press the console in the drill room to spawn the 8 orange keycards. They have 6 possible spawn places above and below ground. BELOW: On top of the crate first left when you leave drill room Inside a breakable crate next to the stairs in the small warehouse Inside the small warehouse vent To the left of the computer in the T Tester viewing room Behind the blue reactor To the left of the pistons in the large warehouse ABOVE: Around the rocks In the moon buggy warehouse on top of the boxes In the leftmost toilet In Hoozain's cafe, on top of the fridge In fang's room (behind the red couch in the bedrooms) Near the playground, in a small alleyway between the fence and the playground Once you have all 8, go to the launch centre (moon cheese teleport) with 4 people. You need to press all the buttons simultaneously. Once you've done that, you know what to do. Big red button! Go go go! Good luck.
