The end of 7 is way different now. No power cords to plug in. A few switches to throw and the power button control panel is down a small ramp now.

Zadkan you saved me hours of confusion. Thank you and have a nice day.

[Murder Squid]

I would have not been able to complete Interloper without this - thanks.

Great videos! But watch out: I have 2022 version. There are differences since 2019. e.g. you get shot gun before magnum early on.

Thanks for sharing this walk through, it was a great help for me. It got me out of lots of tights spots and helped me enjoy the game more.

Chapter 15 at the end, if the short cable does not connect to the broken connection, just kill yourself and load the checkpoint, then I connected first the short cable to the right connection and then to the center. Lastly connected the long cable to the left and top connections.

Chapter 15 at exactly 1 hour, I cannot make this connection with the short cable. I have the long cable connected to the far left and top, and the short cable connects to the center, but will not connect to the far right. I don't know if I'm bugged, or doing something incorrectly, but the short cable will not connect for me there. I'm stuck.

Thanks for taking the time to share your "guide". It helped me several times when I was running in circles trying to survive.
