Please delete if this shouldnt be here but ive seen it with Injustice and AC3 before so....
First, add someone who owns Stryder (we tested it with the gamertag PAULINK) and compare games.
Find Stryder in there games library, click on it to view more then click “Play”
You’ll be brought to the Xbox One games marketplace, where you can then download and play the unreleased upcoming game 100% free.
No word on how long this will work or if Microsoft will be taking it down, but if you want it, grab it while you still can.
