After his first Wolfenstein project Shadows of Destiny has been released only a few months ago, you would consider he will take a short break but little did I know. Just a few weeks ago he has released the first beta version of the successor with the promising title Machines of Death, another GZDoom-project based on the original Wolfenstein 3D with a lot of interesting additions thanks to the new engine-capabilities. He really took the spirit and carried it further. This is a real recommendation if you are into those good old times. Check the development thread and the beta version at the ZDoom forums.
