Is a fair point dude. He does actually say he is a clone, but there are a couple of inconsistencies in the original story. Right off the bat this puzzles me, because who is he a clone of? This implies he must have been a real person to start with. This does fit with the "Created by Horzine" line in the mod, since as a clone he will have be made by horzine, but someone will have had to have existed for him to be cloned from. A modification I would make is Masterson was kileld during the outbreak and the clone was made from his remains
Also the story I have read indicates that he escaped from Horzine via the sewers to try to get revenge on his mad creators. This doesn't work if he entire reason for being created was to destroy the DRF. He completed this task without question and at no point shows any intent of fighting his creators.
Although looking back on it, it would seem some of the sources I have pulled my information from have been altered or are completely missing. Like the clot and its history as a replacement for Kevins lost son, the page about Kevin before he became the Patriarch is gone completely.
I have only ever played the campaign of the mod the rest I have had to piece together from various other sources, these sources may well have been wrong, so I'm not surprised there are inconsistencies.
This was the story as far as I could understand it. When I look at the information strewn across websites now, Kevin seems more like a mad man rather than person who has snapped after losing everything.
I have to admit I am not as big a fan of this tone in the story, but far as I can tell it seems the more accurate to the mod. It kind of has that Resident Evil "because we can" approach to releasing a zombie outbreak, rather than a chain of events that culminates in the release of the specimens.
So I'd be quite happy for someone to have a new whack at it, because from what I can see, everything I really liked and thought was clever and unique about the story seems to be incorrect
