During an AMA (Ask Me Anything) session this week on Reddit, Sony Online Entertainment president John Smedley addressed similarities between their upcoming zombie MMO, H1Z1 and Bohemia Interactive’s DayZ.

He admitted the two games share things in common, even calling some members of the H1Z1 team “fans and contributors” of the ArmA 2 mod.

“Not going to give some politically correct dodgy BS answer,” Smedley said. “H1Z1 is survival in a zombie apocalypse game. So is DayZ. They have made a brilliant game (first might I add). They have a great vision for it and [you] can count myself and most of the people on our team as fans and contributors.”

Pointing out the various zombie movies he likes, he said there is room for more than one game in the genre, and he expounded on what he hopes Sony’s MMO becomes in the future.

“Long term we plan on making this about a persistent world with a big landscape with thousands of players,” he said. “We also want to make sure we have a deep in-game economy that is heavily dependent on crafting. Our goal is to make ours fun, accessible, hard-core and super, super deep. As time goes on, we hope our take on the end of the world by zombie is fun and lots of people get to try it.”

Monetization is always a sticky topic. But Smedley confirmed that staples like food, water, guns and ammo will not be available for purchase, nor will boosts that affect those items.

H1Z1 will be released first on PC and then later for PS4.
