ScrewUp!
The left bundle lead deployment game
Continuous unipolar pacing 2.0 V @ 0.5 ms is running. Screw the lead

and fix it the moment you judge you've reached the left bundle.
Too shallow → no capture. Too deep → perforation.
Your crew: Twiddles pedals the sheath, Breach rides the helix.
Get Breach to the bundle vine — not the goo, and definitely not the lava.
