I can't find my game invites for black ops two does anyone know where to find all my game ...

Where did you find it under, I've gone to games and black ops games and can't find the download for it and it won't let me re insert my code

This discussion is really no concern of mine because I have all 3 games (Black Ops 2, Halo 4, & Minecraft Xbox 360 Edition) & like them all equally for their own reasons. However, I do play Black Ops 2 more nowadays & that is because that is where the majority
of my online friends are - hence, partly why I DO care about the numbers. Why play an online game that nobody else plays? The majority of the Xbox Live Arcade library is a wasteland in terms of finding players online... I know because I have 200+ Arcade games
& can't find anyone to play with online in most of them, whereas in popular games like Minecraft, Halo, & Call of Duty, I can...

The Servers have to be down or at least the Co-op Cause I Still can't find my brothers sign or join session in progress and can't even invite to game

Alright, then it's probably in relation to black ops saves being corrupt.

A way to check this is by following these steps:

1) Go to the Xbox Guide by pressing the big X in the middle of the controller.

2) Scroll over to the Settings tab.

3) Hover over System Settings and press A.

4) Hover over Storage and press A.

5) Go to All Devices and press A.

6) Press A on Games and Apps.

7) Find "Call of Duty: Black Ops" and then press A while hovering over it.

8) Find where it says "Call of Duty: Black Ops Save Game". Now if there is more than one, then that means that you have played Black Ops on more than one account, if there's only one then skip to step 10.

9) If there are more than two Call of Duty: Black Ops Save Game, then find the one where your Gamertag is under how much data is being shown on the right-hand side.

10) If there is a yellow exclamation point where it says Call of Duty: Black Ops Save Game, then it means that your Save Game is corrupted. Now, if it is corrupted, please hover over the Call of Duty: Black Ops Save Game that you'd like to fix.

11) Choose the Option Delete, and I know it seems that it's a "heavy" option, but all you have to do after deleting the Save Game, is starting up Black ops again, and just play as you usually do.
