According to The Old Blood newspaper clip, Castle Wolfenstein Assassin Executed, a terrorist attempted against Hitler and escaped from there alive around last days of 1945. Also we know that he killed Hans Grösse. A good reference to Wolfenstein 3D. But a question still. What did exactly happen? We don't know how did Blazkowicz end into the castle. And less about in which order occurred everything. Was it planned to kill Hitler from the beginning? Or was he sent there after being captured in another place? Maybe the motion comic trailer from 2009 reboot shows part of what did happen?
