=== Call of Duty: Modern Warfare 2 ===

=== PC/Mac ===

To play Call of Duty on a computer, you must first purchase it. There are many ways to purchase COD for PC/Mac: in stores, online marketplaces, and gaming platforms (like Steam). If you're looking to purchase newer versions of Call of Duty, an easier way would be to do so on steam. Some of you might think it's too expensive to purchase a game on steam, and there are ways around this. You can purchase on sites such as [http://g2a.com/ g2a] and [https://www.kinguin.net/ kinguin], which is a large marketplace for selling CD keys; however, these sites often have keys that were refunded or carded, so make sure to know that your game might be revoked if it is. However, if you do wish to play COD with peace of the mind and also support the developers of the game, you <b>should</b> purchase them off of steam or in store.
