Some very sad news unfortunately - Cedric Lutes, who was Zaxtor Znort in the AMC TC as well as Oblivion and Trequonia TC, has passed away. The news came as a massive shock to us on the team, and we give our deepest condolences to his family. Zaxtor was an avid nature enthusiast who loved animals more than anything else; he was also a hard worker and was constantly working on new projects. Whilst the gameplay of his work was extremely difficult, there was a passion and imagination not seen elsewhere in any other projects. Mikko Sandt has done a detailed write up on Cedric and his life on his MSDN site.
Zaxtor Znort will live on in the AMC TC; if you haven't checked out his other work and are looking for some extremely challenging puzzle solving and gameplay, take a look at his work. Rest in piece Cedric.
