I'm pretty sure that, the first map of the game is beatable without any other things than the Drill and the bag (Level 1 Tools). Can someone make a category out of it ? The Rules would be something like :

• Drill and Bag only
• No Loadout
• Stay Silent (No Alarms, No Guards Spotting the Player)

If some people still aren't counvinced i can try doing a run, just need to figure some timings out.
