Oh btw, secret basement alert!!!!!
once you have started the "another piece of the puzzle" quest, go to new haven.
do the normal loot run route, and when you get to the last one, jump down to the little building.
since you are on this quest, the door will open, and theres an elevator.
there will be alot (ALOT) of psychos down here, so watch out, but theres a gun called "rider"
is a pretty awesome gun :3
