Description

Welcome to DeRailer's Development ROBLOX. This group holds Members, Testers & higher roles. How the testing games work. When a test is announced on the dizzy server, the selected game is made public and anyone is able to join. When a session has ended, the game is made back to private in order to prevent people from leaking. How to become a tester? You must be on the dizzy server and find an open application to fill out. Once applications have been read, the trainees must be trained with driving and guarding. (it's fine if you select a single option, you'll be given a role to display what you were trained for)

Membership history

Growth

2 measurements spanning 7 days, net -1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 486–487 and does not start at zero.
