The world's spawn point is located in a 33×33 region centered at X=-208, Y=64, Z=-61. The terrain is desolate, dark, and pockmarked with many failures to get out of the way in time. It also can't be modified, so there is an immediate need to go somewhere bright and free of exploding shrubbery. Two different locations are close enough to the spawn point to reach immediately. Directions to reach each of them are listed below.
The closest inhabited place to the Spawn Point is Mt. Paradox. To reach Mt. Paradox, look for the giant Samus Aran statue. (Click the screenshot to the right for a larger view.) Head in that direction. A road, which is also shown in the photo, provides easier travel than the broken terrain of the spawning area. If it is night time, sprint up the road by double-tapping the forward button.
At the end of the road, turn right and enter the set of double doors.
Once inside, press either of the stone buttons by right-clicking it. The doors will close behind you, and you will be safe. Simply walk forward through the second set of doors and press one of the buttons again to gain access to the rest of the base. Be sure to read all of the notice signs posted in this hallway, as they contain important information about the world. Head downstairs to reach the rest of the base.
