Bad news is there wont be a part 6.
Good news is the series will be remade and fully told.
the majority of part 6 was lost in a computer crash back in the day, which pissed me off enough to quit.
Dead Rain has been a great learning experience for me, it was my first animation and you can see it get better with each episode as I learned.
There is so much more to the story than was shown in these 5 episodes, its really long and epic. The remake will have all of that plus some changes for the better. For example; Clemens having a much larger and involved role :) The remake will probably be in Comic book form.
When will it be made?
I don't know yet.
Whats left of the lost episodes can be seen on my website, so go check it out if your curious.
