An upgrade route has several independent checks
- Identify the relevant map and BO1 build; do not import a remake’s route.
- Confirm the needed route is open and the required power/transport interactions actually succeed.
- Reach the machine and capture its readable prompt, price and time/access constraints.
- Keep enough points and ammunition for the return route.
- Record the weapon before and after upgrading, then test the behavior you intend to describe.
Where to investigate next
| Map | Progression theme in the archived description | Still needed |
|---|---|---|
| Kino der Toten | Power, teleporter and upgrade access | Assisted power/link/ride, 5,000 upgrade, retrieval and automatic return observed; normal continuous survival pending. |
| Der Riese | Teleporter network and mainframe | All three links, final gate, 5,000 upgrade/retrieval and 1,500 return ride observed with assistance; timed walking returns pending. |
| Ascension | Lunar landers and rocket sequence | The required lander/rocket interactions and resulting access. |
| “Five” | Floors, elevators and DEFCON | Switch conditions and safe access in solo. |
| Moon | Area 51 and the lunar base | P.E.S., power, both transport directions and a separate 5,000 upgrade/retrieval → Moon case observed with assistance; one continuous survival round trip pending. |
Why there is no universal browser cost table here
The three tested machines each displayed and deducted 5,000 for the first upgrade. That does not establish the price or behavior of upgraded ammunition, every weapon or repeated upgrades. Those remain separate checks.
The objective checks used god mode, debug points and position jumps. They did not force power/link flags, but they also did not prove an unassisted walking route or high-round survival. Failed and repeated interactions remain in the dated record.
