Each pack contained a Promo Active Card. The price of the pack was set at $9.99. The money collected through those sales mostly served to finance the development of the game. Promo cards were mostly used to promote the game and its upcoming features. Additionally, promo packs were used to create so-called investors: anyone who managed to get 10 Promo Active Cards automatically received the status of Investor. Investors had access to exclusive NBM sales. Later, with the introduction of ranks, anyone owning 100 PROMO cards can unlock the INVESTOR [achievement](/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/xi-achievements-and-ranks/achievements.md), granting a significant amount of experience for Corporal ranks.
