Rainbow Six Extraction
Microtransactions in Rainbow Six Extraction are summarized as...
The game features multiple Deluxe Editions. Some of these unlock cosmetics between both this game and Rainbow Six Siege.
Some cosmetics can be earned in-game by leveling up your character. Each character needs to be level up individually. This is a slow process but this can be sped up by purchasing XP-Boosts.
Other cosmetics need to be purchased through the in-game store. This can only be done by purchasing the premium currency. The amount of currency you purchase do often not match the cost of the items. Resulting in you having to spend more than you would need to.
