I've just received an Xbox debug kit which contains two builds of Batman: Dark Tomorrow (HotGen Studios, published by Kemko). It boots to a title screen containing a level select, has a long intro FMV (looks fairly polished) and then into a very buggy and crashy game.
I haven't played the finished game so not sure what's different about this build. Anyone interested?
If these kits have some sort of screenshot functionality over the network (like the 360's do) I'll gladly post some shots, just need to find the XDK for it first.
