We should note that this doesn't mean Modern Warfare III alone will take up 200GB of file storage though  the base installation for Call of Duty HQ (the central hub needed to access Modern Warfare II, Modern Warfare III, and Warzone) is roughly 50GB.

However, typically, Call of Duty Mobile requires around 2 to 3 GB of internal storage space for installation. It's worth noting that the game's size may increase over time as updates and additional content are released.

The Campaign consists of 14 different missions. All but one of these missions reward players with the following items upon completion: Operation 627: Breather  Calling Card. Precious Cargo: 30 mins Double Player XP Token & 30 mins Double Weapon XP Token.

When focusing on the main objectives, Call of Duty: Modern Warfare II is about 8 Hours in length. If you're a gamer that strives to see all aspects of the game, you are likely to spend around 24 Hours to obtain 100% completion.
