Assassin's Creed Unity credits are used to speed up game progression

Ubisoft's just-released title Assassin's Creed Unity is trying something new for the series - microtransactions affecting gameplay.

While Assassin's Creed: Black Flag allowed players to spend hard-earned cash on cosmetic items, you can now spend real money, via the 'Helix Credits' proxy currency, to unlock upgrades without having to go through the pesky business of actually playing the game.

Everything is balanced in a way that the player will never feel forced to buy, but rather to keep playing the game to access better gear and become stronger.

Monetization in ACU is limited to time-savers (access to advanced equipments earlier, etc).

Helix Points can be bought in-game, costing between $19.99 and $99.99, depending on how many you buy.

Back in my day, all of this would've been achieved through cheat codes. Grumble.
