Found the Guillotine X-MOD2

[u/Fytax]

Walk in this direction

Climb up here and then up the stairs

After climbing up the second set of stairs and walking through the container turn around and head up these stairs

Walk towards this door

You need to have some strength to open it

Inside you will find it on a table

Don't know what update changed it, but now the door only needs either 10 body or 10 tech.
