Where is the buyable ending been searching everywhere and I don't think you put one in, also buildible the mystery box cannot even use it at all I found two parts of it, am I missing another piece for it to work?
- Spawn room in the corner next to the lonely window
- Thompson room in the Lab section of the map
- In the corner near the riser in the room right before the room with the buildable table
Go to the Pack-a-Punch pool and as your looking at Pack-a-Punch, there will be a wall to your right. Go up to that wall and there will be a 1k point trigger. Buy the trigger and then head to the stairs outside of spawn in the Double Tap room. A door underneath the stairs will have opened and the endgame switch can be purchased for 50k.
