can anybody make a good zombie game that is actualy decieant?
I think that the theme and storyline are a problem, it's really hard finding an unusual idea about that and also making an amusing and challenging game.
If you want a decent zombie Flash game try Last stand 1&2 or Endless Zombie Rampage. If you are looking for a decent Video/Console game try any game from Resident Evil series or House of the Dead series.
The only problem with Zombie games is that the developers seem to think that the addition of a zombie completes they game, and they end development. Last Stand and Box Head are the only good zombie games in my opinion. At least flash wise. There are some good ones for the Xbox. Left 4 Dead being one.
Pure zombies? Like eat your flesh zombies? Not sure. I've played resident evil 4 and 5 and they were awesome, but the "zombies" are made by parasites, and they use weapons, and they can talk, etc. So I wouldn't really consider them zombies.
