Sony's H1Z1 plagued by technical issues at launch

Zombie survival shooter is the latest big game to stumble badly at launch

Sony Online Entertainment's H1Z1 has become the latest in a string of recent games to launch with significant online performance issues.

The zombie survival MMO's problems became apparent almost immediately after it was released on January 15. Login problems were widely reported, as was the ability to actually see active servers. There were also performance issues for those that made it into the game, including low framerates, no voice chat, and slow responsiveness among the zombie NPCs, among others.

SOE president John Smedley's Twitter feed has been a blur of updates and apologies since then, with the H1Z1 team working throughout the weekend.
