There's really no reason beyond apathy that Steam Deck players aren't able to use the service, all because one person decided to cheat with the same model of computer. I was hoping that when I reinstalled bo2 zombies it would let me play given that it's a co-op mode, but nope; still banned. For a client that is supposed to bring life to abandoned games, it just leaves a sour taste in my mouth when I basically get the Activision treatment from you, and directed to install an entirely new Operating System as if that's an acceptable solution for a game that for all other intents and purposes works fine on SteamOS. There are thousands of people that want to play their old favorites but instead we get told to kick rocks because one guy decided to try the incredibly rare act of cheating in a multiplayer game? Come on now.
