Call of Juarez: Gunslinger is one of the games I don't think about too often, but when I do, I think "yeah, you know what? That game was fun." Unfortunately, it seems like fewer people will be able to experience that feeling, as it's been delisted from major console online storefronts.
The game seems to have been delisted from Steam, PSN, and Xbox Live early Friday. Currently, searching for the game on the PSN store does not bring up results for the game, though it's been available on the storefront before. On Xbox Live, you can find its official store page, but all you can find is the demo. You can also find the demo on Steam if you type the name into the search bar, but clicking on the link to the demo will bring you back to the main store page. The rest of the Call of Juarez games are still available, however.Wario64 on Twitter, (2)]
It's entirely possible this is one of those slip-ups you could chalk up to negligence. But considering it's effectively gone from everywhere except Uplay (where it's on sale as of this writing), it's easy to see this as a move to make Uplay games more exclusive… but that doesn't seem right either. If that's the case, why Gunslinger, of all games? I'm going to guess this is negligence or some lapsed licence agreement.
