The Steam Deck is finally in the hands of some lucky customers who were able to be part of the first wave of releases.

This news may be disappointing, but it doesn’t come as a complete surprise. Former Halo developer Bungie has also prevented Destiny 2 from being playable on the handheld.

Halo Infinite players have been complaining about issues with cheating over the last few months. 343 Industries recently acknowledged this problem, and reaffirmed that it is working to solve it.
