Assassin’s Creed 3 includes micro-transactions
A Marketplace listing for Assassin’s Creed 3 has shown that players will be able to buy “Erudito Credits” to unlock higher level multiplayer items.
These credits will be able in 20, 50, 155, 380 and 925, which provides plenty of options for you to choose from. The most expensive pack costs 1600 MSP.
This is a good way for players to get better items, without dedicating time they don’t have into the multiplayer. We don’t know if these credits will be used on the single player, so Ubisoft will have to clear that up.
