Now that Marvel's Avengers has released in Australia and other parts of the world, we have learned a little more about the game's microtransaction system and how much things actually cost.
The in-game currency is called Credits, and, like many other games that use microtransactions, you can buy the Credits in various allotments. From the in-game store you can purchase Credits in groups of 500, 2,000 (plus 200 bonus Credits), 5,000 (plus 1,500 bonus Credits), and 10,000 (plus 3,000 bonus Credits), according to Stevivor.
In terms of pricing, it begins at $5 USD for 500 Credits and scales all the way up to $100 USD for the package of 13,000 Credits.
