Okay, I propose this course of action:1. Arm everyone with guns (except for the Lunatic, probably)2. Plant an explosive charge on the stair-gate3. Repeat 2 as we move up the floors4. Get to the control room.5. Kick down the door and go in guns blazing6. Kill the Mastermind7. Escape the school with more explosives.Alternatively, just skip 3-6 by planting the explosives at the door. Or a wall.

Can't, we would first need a science lab to make explosives, and I doubt it's on the first floor, 

2, if we blow something up then it would be counted as vandalism and the person who planted them would be speared, 

3 we would need metal for guns and bullets and I doubt that the workshop is on the first floor

4 even if we could find enough materials for bombs and enough for guns, I highly doubt the mastermind wouldn't have a trap door or a panic room that they could hide in if we get to them. 

5. if we get to the mastermind and kill them I don't think we would have enough resources as in bombs to blow through steel that thick and get through the windows, and if we blow through how do we know if we want to go outside and see what it is like.

6 Even if all of those could be done, I doubt MK would let us make guns, and if it did that would be dumb as hell, and he would probably temp us to kill each other with those guns. 

7. I really doubt MK would let us make bombs as well since they could be used to either escape or make a way to the mastermind

8. You should think of a better plan, because we have people willing to kill one another and think of it as fun and when MK brings the incintive out it would be over if we have guns or bombs.
