DayZ, although that one's pretty cool too. There's a new kid on this particular genre block, and it's an MMO called The War Z. It's brought to you by Hammerpoint Interactive and Arktos, and IGN has an interview scoop with a couple of the principals.
"We started thinking about doing a zombie game last year and began developing a quest-based MMO set in a large, zombie-infested world. Players would be able to explore and unlock new areas on the map as they progress through quests assigned to them in-game," explains executive producer Sergey Titov.
What about the DayZ connection? There really isn't one aside from coincidental timing. DayZ is a mod for an existing military sim title, whereas The War Z is a stand-alone MMO with a dedicated team behind it (and an upfront cost of $29.99). Is it really an MMO, though? That's in the eye of the beholder, we suppose, but it does have a huge open world, PvP, and the ability to support 250 players per server. The War Z also features dozens of skills and social niceties like bounties and in-game notes (no profanity, though; blowing off zombie heads should never result in inappropriate language).
If the War Z name sounds familiar, it might be because you're thinking of Paramount's World War Z property that we've talked about before. As with DayZ, though, the two projects are unrelated save for the similar names and the horror sub-genre.
The War Z is currently undergoing internal alpha testing, with a closed beta expected later this summer. IGN says the final game will be out "before the end of the year."
