u will not be able to leave the chamber otherwise as even if u have stolen keycard, when in 914 and change it to any level, it will not access 914 door
loosing the hacking device will force you to use the 1:1 teleport, which can lead you to the inaccessible room in phi.Remove this 1:1 teleport location
you can get the hacking device back from 914, it’s just you have to keep upgrading over and over, so whatever gun you had is likely to be changed to something else, or lost.
yeah and it’s always the good guns without hacking device (like aa-12) and the shitter ones that have it so it’s really annoying as you have to sacrifice a good gun or the hacking device
