“We got the chance for extra testing time & grabbed it,” the company stated via its Twitter account.
Undead Labs also said it’d announce a definitive date for the DLC’s release once certification testing was almost complete.
Just earlier this month, the company said that State of Decay update TU4 would arrive shortly before Breakdown’s launch.
The DLC is expected to make the game more challenging to survive in as gamers progress through State of Decay.
Undead Labs previously discussed specifics of Breakdown in a blog post.
State of Decay has now generated over one million in sales since initially arriving for the Xbox 360 back in June.
