in surf maps most prisons have a key pad or a set of things needed to be done to activate the kill switch.

I know of 1 but wish to expand this knowledge.
The 1 i know is in year 3000 were there is a key pad, The combo is
left, right, middle (top row) left, right middle(bottom row) left, right middle(middle row)
After that the alarm sounds and rows of deadly boxes come and kill peepes in prison

if you no any other combos or routines plz post "i gotta catch 'em all"
