505 Games and Overkill Studios managed to score major cash with Payday 2 – without needing to don a mask or carry heavy weapons.

The highly anticipated sequel, which focuses on a team of four men completing dangerous heists, racked up a promising 1.3 million units sold in its first month of release – a huge increase over the original’s sales. For good measure, about 80 percent of those sales came digitally, including a large amount of buyers on PlayStation Network, Xbox Live and Steam/PC.

Payday 2’s lower retail price probably has a big part to do with that, as the game sells for $39.99 — $20 lower than the usual industry standard. Another deciding factor is its huge multiplayer appeal, as players can team up together to complete robberies and other heists, with capacity for up to four players.
