The Control punch card puzzle is something you'll come across during the Old Boys Club mission, where there's a HRA Machine that needs fixing. If you don't know what you're doing then you might end up getting frustratingly stuck, as it isn't obvious how you go about solving it if you don't manage to suss it out. The same could be said about much of the game to be honest, as Control is anything but straightforward.

Anyway, it's the Control punch card puzzle we're looking at specifically here, so if you need a hand getting through it then you've come to the right place. It involves picking up the aforementioned punch cards from around the lab, then inserting them in the correct terminals. If you're wondering what the solution is to the punch card puzzle with the Control HRA Machine, keep reading for an explanation and the solution.

Alright, so you've made it to the HRA Lab and you've solved the previous cube puzzle. You now need to fix the HRA Machine, which involves picking up the five Control punch cards littered around the lab – the easy part – then matching the punch cards to the numbered terminals – the slightly harder part. Take a look at the list below for where to find the five punch cards:

  1. On the floor by the doorway to the staircase leading up
  2. On the ground floor, on the desk to the left-hand side as you enter the lab
  3. On the corner of the brown table on the ground floor
  4. On a white box on the right-hand side of the ground floor
  5. 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 terminal. Each number is the terminal that punch card should go in. If you just want a clue to try and figure it out for yourself though, then pay attention to the whiteboards around the lab. They provide contextual hints as to what goes where.

Give me a game and I will write every "how to" I possibly can or die trying. When I'm not knee-deep in a game to write guides on, you'll find me hurtling round the track in F1, flinging balls on my phone in Pokemon Go, pretending to know what I'm doing in Football Manager, or clicking on heads in Valorant.
