Iron Blight Workshop Route: Punch Card, Blowtorch and Exits

At the Iron Blight factory, enter 45107 at the Punch Card machine, collect the finished card, use its door reader and check the barrel after the drop for the Blowtorch. Bring the Workshop route key from the apartment chain and leave inventory space for both the card and the tool.

The preceding apartment key route ends with the Block B windowsill key. Check that pickup before returning toward the factory; the A.96 connector key alone only advances the crossing between blocks.

Workshop route at a glance

Checkpoint	What you need	What to do next
Industrial approach	Workshop Alley Key	Follow the workshop access route rather than testing the key on unrelated Prasnova doors.
Brick office	Nearby Override Protocol	Read the document before using the green Punch Card machine.
Punch Card	Completed card in inventory	Interact again to collect the machine's output, then use the matching exit reader.
Blowtorch route	Space for another tool	Continue past the card gate and keep the Blowtorch for its intended sealed-metal interaction.

Enter the workshop with the right inventory

The Workshop Alley Key appears after the Connector Key and Large Backpack portion of Prasnova. The key is route-critical; a nearby gun or attachment is optional. If your grid is full, install a compatible attachment, store a weapon whose ammunition is unavailable, or leave a clearly optional pickup for a later return rather than dropping the key.

Patch 1.04 added a map objective pin for the Workshop Key. That pin helps you return to the correct objective, but it does not replace checking the item's name and the current route text. If an older video lacks the pin, compare landmarks rather than assuming the route changed.

Find the brick office and make the Punch Card

Follow the raised metal route into the small brick office with yellow lockers, green cabinets, and a green machine on a desk. Read the Override Protocol, then use the Punch Card solution for the field order and recovery steps.

Do not leave when the machine appears to finish. Interact again to take the completed card. Patch 1.01 fixed a launch bug that could reject a correct first attempt, so restart Steam before assuming the document or route is wrong.

Leave the card gate and collect the Blowtorch

Use the card at its matching gate reader, then continue toward the Blowtorch. Patch 1.04 added a map pin for this objective as well. The Blowtorch is a progression tool, not a substitute for the Crowbar or Bolt Cutter; hold on to it until its matching heat-cut or sealed-metal interaction has completed.

The Workshop can create sudden inventory pressure because the key, card, and Blowtorch arrive close together. Make the space before entering the office rather than discarding a completed route item afterward.

Already left the Blowtorch pickup area?

The community route places the Blowtorch on a barrel after the drop beyond the card door. Check that barrel and the map objective pin before continuing out of the pickup area. If you have already left it without the tool, keep the current progress and look for a reachable return path on your map. If none is visible, check for an existing checkpoint before the card-door sequence and reload it only where your mode permits. Keep that checkpoint where possible until the Blowtorch is in your carried inventory; jumping through geometry is not a reliable way to recover the objective.

After collecting the Blowtorch, the MP5 pickup guide adds a separate Village detour. Take that return trip for collection; skip it when following the Red Express timed plan.

Workshop door or route not advancing

The October 17 update removed accidental quick save/load in Prasnova. Check the save options your current mode offers and the location of an existing checkpoint before testing the factory door. Do not assume you can create a separate manual save at the machine; use Save & Quit and checkpoint checks.

1. Confirm that the Workshop Alley Key, Punch Card, or Blowtorch is carried rather than stored.
2. If an earlier checkpoint exists and your mode permits loading it, check that it predates the affected machine or door. Keep it where the mode allows while testing; confirm the carried route items after loading.
3. Update Steam. Patch 1.02 included a possible fix for the Workshop wire door, and Patch 1.04 fixed additional factory-door and mutant-pathing issues.
4. Re-open the map to check the Workshop Key or Blowtorch objective pins on a current build.

Where the Workshop leads

The Workshop is part of the broader Prasnova route. After the industrial chain, use the Police Station location guide for the camera-panel area, or open the full walkthrough for the next mandatory objective. For every route tool in order, see key items.

Evidence boundary

The official Steam announcements document the map pins and intended patch fixes; they do not prove that every current door or save fault is resolved. Room landmarks and route order retain their September 6, 2026 completed-route evidence. The October 17 developer announcement was rechecked October 21, 2026 for the Prasnova save change. Apartment-to-factory source links retain their October 19, 2026 review; neither review replayed this route. Report a discrepancy with your game version and current objective so the route can be retested.
