How to solve the Cable and Battery Puzzle in We Were Here Tomorrow (Chapter 3)

Chapter 3 of "We Were Here Tomorrow" presents a complex Cable and Battery puzzle in the RD facility, requiring players to activate a specific sequence of modules to unlock three doors: GRE, RED, and BLU. Each module has a unique ID, and activation must follow a strict rule: only a module connected to the last activated one can be chosen, and each module can only be visited once starting from GEN. Unlocking the GRE door requires activating Σ02, which then opens access to Θ01-Θ04. The RED door needs Σ03 to be activated, providing access to Δ01, Δ03, and Δ04. Finally, unlocking the BLU door involves activating Δ03, which then makes λ01-λ03 available. The ultimate goal is to activate all modules exactly once, following a specific order to visit Ψ02, Θ03, λ03, and Ψ07. The complete solution provided is: GEN → Ψ01 → Ψ04 → Ψ02 → Ψ03 → Ψ06 → Σ04 → Σ03 → Σ01 → Σ02 → Ψ08 → Θ03 → Δ02 → Δ03 → λ02 → λ03 → λ01 → Ψ07.
