Not really a quest, but the pack-a-punch room is opened in the mule kick room when power is turned on (power is also located in the mule kick room).


Part locations are the same every game.
-One is directly in front of you when you enter the mansion.
-One is on the bookshelf farthest from the restroom in the lounge/library.
-One is right next to the bed in the "golden bedroom".
The shield can be built in the main hall that contains widow's wine.


Look inside the opened stall in the restroom.


To unlock the buyable ending, you must first collect 7 plane parts.
-One is right under the archway, on the table outside of spawn.
-One is to your right when you enter the mansion.
-One is to your right when you go upstairs in the mansion.
-One is on the bookshelf closest to the restroom in the lounge/library.
-One is adjacent to double tap in the bar.
-One is on the non-rocket shield buildable table in the main hall.
-One is to your left when you enter the mule kick room.
These parts can be collected in any order and when each one has been collected, the white door on the back side of the mule kick room will be opened; revealing a buyable ending.
