Item description:

enter the building and go to the galactic trade
on the wall to the left.

Sell anything from the inventory and the trophy
will pop.


Note that these were made using Version 1.0 of the game. This version is extremely glitchy and at times, may crash.
If a save doesn't work properly, reload it from last save point and it should work just fine.
I made them using this version as its a lot easier than the recent updates.
I recommend playing on the base version of the game if you have a disc.
