The source does not publish a more complicated checklist. To minimize ambiguity, do not select a standard or Special-Ops class and do not let another player join the attempt.
Attempt plan
Remove avoidable failure points
- Create or join a private server and confirm you are alone before spawning.
- Remain classless rather than relying on edge cases around other class states.
- Follow the two-generator, basement-valve, Sector 2 upload and Sector 3 route.
- Do not assume a disconnect or late join preserves the run; restart if the server state becomes uncertain.
- After the clear, confirm the achievement and class availability before leaving.
The restart advice is precautionary. The source confirms the core requirement but does not document every disconnect or join-state edge case.
