It's been an open secret for quite some time that Valve is working on a game called Deadlock, but the studio only just officially announced its new game today. That said, it wasn't much of an announcement, as the game's existence was quietly confirmed by a mostly empty Steam page, which says that Deadlock is "a multiplayer game in early development."
"Deadlock is in early development with lots of temporary art and experimental gameplay," reads a notice on the Steam page for the game, which went live on Friday.
