anthonykojima hi, glad you like the design I am working with a couple of excellent artists so hopefully more game assets will be coming soon.
Anyway the game will feature both survivors and creatures, zombies naturally will be included, demons, the devil, angels, various mythical gods and some other things.
I like your idea of the different survivors the game was for the most part going to see the player trying to survive alone. But including some other survivor characters is a good idea, both good and bad etc.
P.s. I have purchased a license... Originally i did it just to support development, but I am generally glad I did as some of my games even the fluxation one just keep getting bigger and a license is a must have to really get the most out of the software :)
