Research Center Exchange ico

The Research Center Exchange is a shop that can be accessed by interacting with a yellow cash register on a table located near the middle of the Research Center.

Unlike most shops, it takes Data Discs instead of Gols as currency.

Relationship discount[]

The player can get up to 20% discount when shopping at Research Center Exchange if they become good friends with Petra and 25% discount if they become lovers.


Unlike most of the other stores, Research Center Exchange does not purchase any items from the player.

General stock[]

The store is stocked with small amount of relic crafting materials and several crafting books. Not all items are available for purchase at the beginning of the game, a few of them are unlocked as the player progresses with the main story.

There is a fixed amount of each item in stock. If the player buys all available items they will have to wait until the next day for the store to restock.

Advanced Engines, Silicon Chipsets and Condensed Power Stones can all be found in Abandoned Ruins and some other places, though they are relatively rare early on, which can make them worthwhile purchases.

Assembly diagrams

All of the assembly diagrams can be obtained for less Data Discs if obtained from Petra during a mission, though the player will have to wait at least one day for each blueprint.

However, if the player's game is bugged and they cannot otherwise receive a blueprint they need, they can simply buy it from this store.
