It seems with the popularity of Walking Dead and DayZ that there is a new genre of videogames branching out of the normal Survival Horror. What genre you ask, Zombie Apocalypse Survival Simulation. Yeah yeah, but there are so many Zombie survival games, how is this a new genre? Simple, it's an actual representation to what a Zombie Apocalypse may be like that. It's not some arcade shoot everything with infinite ammo game.To get what Zombie Apocalypse just look at DayZ.
DayZ is AWESOME. However, it is so difficult to get into a game. It's 50% server searching, 40% playing and 10% worrying about getting disconnected everytime you see that damn broken red chain link. It's "alpha" yeah, I understand. Personally I'm thinking it's an experiment while Bohemia finishes up Arma 3 and any final DayZ release will be on that engine. Hell, i've read Rocket was moving his things to the Bohemia offices so maybe he's working with them for a full on Arma 3 engine Day Z release.
But until then, we still have a flawed but awesome game to play. But it's not the only one anymore. Here comes, The War Z. Originally being designed as a Zombie Survival MMO with quests and unlocked areas. But after DayZ they made some design changes to reflect what is making DayZ so popular and design changes that seem to be on players wish lists. Either way it'll be interesting to see how it plays and maybe even get Rocket to make DayZ even better now that their will be competition.
