If you thought Overwatch, Blizzard's insanely popular class-based first person shooter, would escape the microtransaction bug that's infected so many multiplayer games, you'd sadly be wrong.

While you can still gain loot boxes from leveling up, you can also opt to spend money for more loot boxes. The prices are as follows:
