Xbox Microsoft Store Game size

Hi there Zero welcome to the community forum! Christopher here, an Xbox fan and been on Xbox for years already. I would really love to make your day by helping you out. I completely understand were you're coming from; the size on the Microsoft Store is accurate for the first "version" of the game.

Call Of Duty Modern Warfare is a clear example of what you are stating; the game weights around 20 G.B but after the updates it almost is 100 G.B! Why do Microsoft doesn't put the final size of the game on the store? The answer I got it from Xbox support and they told me that this is due to how unpredictable updates are, a developer/publisher can update his game 10 times a week, making this the game heavier or lighter! And Microsoft would have to change the size everytime, updating the store as well.

So yes, this is a reason, I completely understand your concern, I was on the same spot as you are, unfortunately right now the only way to know the real size of a gane is to download it ourselves! Or try to find the final size on a forum! (But like I said, there are a lot of updates for games so the forum size might be outdated.)

The game install sizes are also listed on the Xbox One game store, on the console and here on Xbox.com. The download sizes are exactly the same as the disc install sizes.

As to the install size to actual game size ratio, that one is easy to explain. The size of a game install isn't necessarily bigger because the game is 'bigger'. The size really depends on the game assets, things such as textures, high definition audio and
HD video sequences. This explains why AC4 is 7.63GB on Xbox 360, and 20.81GB on Xbox One.

Don't believe so, but I'm not entirely sure.

I know you can look them up online.

The size of the game is actually quite huge. So what happened is they've split it up. You've downloaded the first part which is the single player portion of the game. When Tuesday rolls around you'll start downloading the second part which is the 20GB
multiplayer portion of the game.

The game size is correct...the Steam page (assuming it's the same game) lists:

"Storage: 300 MB available space"

This is the game on the Xbox page, which states only 199mb needed:

Death In The Water 2 just released and is a significant size upgrade on it's predecessor with a 7GB install size
