The gun can now be obtained by putting the Micro HID on very fine
Just remember it wont guarantee you it.
A (rather sloppy) video demonstrating the 3-X Particle Disruptor added in the SCP:SL Christmas Update
extra stuff:
It can break doors, But not locked doors (aka Keycard doors.)
Does not spawn in the map*
