The Control punch card puzzle can prove to be a tricky one, which you'll encounter during the Old Boys Club mission and involves trying to get an HRA Machine up and running again. The fix you need to apply isn't obvious at first, so it can be easy to get stuck here as you try and put the information together. To move forward, you'll need to collect the various Control punch cards from around the lab, before working out the correct terminals to use them on and inserting them accordingly. While there are clues dotted around the area to assist, they're not clear either, so if you want some pointers or the immediate answer, we've got the solution for you here.
Control punch card puzzle solution
You'll arrive at the HRA Lab after solving the previous cube puzzle and need to fix the HRA Machine. This involves picking up five punch cards littered around the lab and then matching the punch cards to the numbered terminals. Here's where to find the five punch cards within the surrounding area:
- On the floor by the doorway to the staircase leading up
- On the ground floor, on the desk to the left-hand side as you enter the lab
- On the corner of the brown table on the ground floor
- On a white box on the right-hand side of the ground floor
- Upstairs on the small wall by the window overlooking the main lab
The image below has the solution for which punch cards go with which number terminal. If you just want a clue to try and figure it out for yourself though, then pay attention to the whiteboards around the lab which provide contextual hints as to what goes where.
Enter those Control punch cards into the respective terminals and voila! The HRA Machine will be fixed and you can progress.
