Ok so I went to check the price of the Master Chief Collection for the summer sale and instead of a price it just had a "Manage" option. Curious, I clicked on it. It then gave me the option to install it. For the heck of it I tried it, and it worked. I just got the master Chief Collection for free. I have never previously purchased it, I have never played it. Did this happen to anyone else? If you have not checked yet, do it. It might be free for you too!
