Control punch card puzzle 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:
- 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 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.
Enter those Control punch cards into the respective terminals and voila! The HRA Machine will be fixed and you can progress.
