Remember late last year when Epic took a scythe to its back-catalogue, delisting almost every single Unreal game? At the time, the blow was softened by the news that Unreal Tournament 3 would become Unreal Tournament 3 X, a free version of the classic with full crossplay between PC storefronts, zero microtransactions, and "no strings attached".
It was never really announced by Epic, mind you. Fans got wind of it thanks to the Steam description for UT3 (visible in this archived version), which was updated around the time Epic was going on its delist spree to include a full description of the new version. I guess there was a reason Epic never made a big splash about it, though, because it now appears to have been memory-holed.
