CG writes: Ubisoft allows gamers the choice of grinding through their Ghost Recon Breakpoint game to earn Skell credits. Players gain the in-game currency by completing missions and collecting items. The shop allows you to spend these points on various weapons upgrades and gear both useful in the field and cosmetic. Alternatively and for some exclusive gear, players can spend upwards of £67 in one denomination of Ghost Coins to purchase gear and useful time-saving items.
