Cyberpunk 2077 was one of the eight best games of Gamescom 2018, reckoned Samuel and Tom. From Cologne, we learned developer CD Projekt Red has "just not been ready" to show off the shooter RPG's elusive demo footage—but it seems an incomplete version is now playable from start to finish. 

As reported by Engadget (via IGN), the game's producer Richard Borzymowski says this playable build is without final assets and is yet to be playtested. But after six years of work, a long spell of silence, and a flurry of excitement and anticipation, this marks a milestone in its development.
