A new Overgrowth a127 video changelog on the Wolfire Games Blog shows a playable alpha version is now being tested for Overgrowth, a 3D action/adventure coming to Windows, Mac, and Linux. Word is: "Don't forget that you can help support us, try out our weekly alphas (such as the one in the video), and chat with other preorderers in the Secret Preorder Forum by preordering Overgrowth. If you'd like to see real-time news about Overgrowth, you can follow me on Twitter at @wolfire." Thanks Ant via Rock, Paper, Shotgun/LinuxGames.
