Before you go to space, you may need to clear some space. Update: We're able to pre-load Infinite Warfare on Steam now (it wasn't showing up in our library earlier, but a restart fixed that), so we have more accurate sizes. On Steam, Infinite Warfare requires 74.2 GB, the Modern Warfare Remastered campaign requires 44.9 GB, and the Modern Warfare Remastered multiplayer requires 25 GB. So, that's about 144 GB total, nearly what's advertised on the Windows Store. However, when actually downloading them, the files are 54.7, 21.7, 20.8 GB respectively, for a total of 97.2 GB for the whole package. Infinite Warfare, the Modern Warfare campaign, and the Modern Warfare multiplayer can all be downloaded separately. (Additional update: Now that I have unpacked the compressed Infinite Warfare download, which took nearly an hour, it's 70.3 GB.) Original story: Call of Duty: Infinite Warfare is a very big game. Though it doesn't seem like its Windows Store entries are meant to be live yet (searching for them in the store returns nothing), we stumbled on them earlier today and found a few different versions of Infinite Warfare with size estimates of up to 149 GB. On Steam, the system requirements ask for 70 GB of free space. The smallest estimate we found on the Windows Store, however, is 93.1 GB, which is for the basic edition of Infinite Warfare which doesn't include Modern Warfare Remastered. PC GAMER
