Crytek's Xbox One launch title Ryse: Son of Rome will include micro-transactions within the game's multiplayer mode.
Players will upgrade their multiplayer characters via blind booster packs of armour upgrades, bought via in-game coins.
You'll accumulate this currency naturally, but can pay for more with real-world money, Microsoft told Videogamer at Gamescom 2013 today.
The system will be similar to FIFA: Ultimate Team or Mass Effect 3's multiplayer packs, with random sets of loot worth varying amounts. There will be different tiers of packs, too - Bronze, Silver and Gold - with the latter naturally affording the best chance at rare items.
Through this system you'll be able to improve your armour and also customise your look.
Eurogamer went hands-on with Ryse's single-player mode last month, when Wes described it as a "flashy but basic brawler that benefits from a twist of strategy and a dash of skill".
