I was promised a position higher up... But that foul dog got it, I will show them... I will show them all! The power of genetic manipulation! This experiment is definitly going to get me my well deserved job! I am just missing a few vital pieces in this puzzle.

I got it! The final vital piece in this genetic puzzle was human blood! I've secretly used my own to produce a new human being, a better human, a stronger human! Although it shows genetic differences, and also visual differences this creature no longer has the desire to feed, nor sleep! The boss is really going to enjoy their new soldiers!

The boss was not pleased... The subjects were too clever, they rebuilt themselves and are wreaking havoc among us! Somehow they ignore me however, is it because they're born from my blood? Or do they just need me? Either way they're killing everyone around us... I will take this journal along, and write down important changes which I might occur. If I don't make it, and you find this... Please, do NOT make the same mistakes I did. I've included my research in the back for future reference.

The above journal entries are used for this games story, you are Cale Neuron, a highly skilled army scientist that's in Despair(Zetsubou in Japanese) for being turned down on a job he was promised, then his new research turned out to be a horrible mistake, and he gets out of his lab to set things straight where possible, with any means possible.
I know it's rather cheesy, but oh well. It does the trick

I plan to do this game with purely stock X10 media, just to show that you do not NEED to get any model packs to get a decent looking original-ish game level.
Anyway, here's a few screenshots from the first(intro) level, which is rather short but will have a few voice parts that lead you into the game a little.
Note that I haven't really worked with FPSC for over a year, so my mapping skills might be a bit icky, I am however open for suggestions and will do my best to get it running properly.
It's not the world that turns against you, it's you that turns against the world.
