Previously known only as Project Z, the title has since been revealed as Left 4 Dead: Survivors. No other details about the game were provided, though the website lists "2014 outbreak coming soon."
Valve and Taito previoysly collaborated on Half-Life 2: Survivor, an arcade game based on Half-Life 2. Released in 2006, the arcade game featured a Story, Battle and Mission mode for players to explore.
In February, Taito released a Japanese teaser trailer for Project Z featuring zombies roaming the streets. You can watch the trailer below.
