Item description:

enter the building to the right.

Speak with the Alien that is asking for Units
to trade for Technology (he is a light blue colour)

Make a selection, either Weapon or suit upgrade
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.
