Not knowing the game, I'm coming at this purely as a fan of the zombie genre. Therefore its probably not too much of a surprise that I find the 'giant sinister corporation' subplot, the sub-Matrix gymnastics and the various mutants and devil dogs a distraction from what was a fairly decent scenario, but they work well enough in context, and I guess it wouldnt be the film of the game without them. There are occasional problem with the editing, which is quite messy in places, but the action rattles along well enough. There are nods to 'Terminator', 'Escape From New York' and as mentioned, 'The Matrix' in here, perhaps betraying a more mainstream lineage but on the plus side, there is much more focus on the action in the streets as the virus takes hold. The lone survivor desperately seeking shelter and isolated pockets of cops fighting pitched battles against the rising hoarde that the 'Day of the Dead' remake (while excellent) only briefly touched on. So while this film isnt perfect, its good enough, and zombie flicks, let alone good zombie flicks arent common enough for fans of the genre to be too judgemental.
