Our four survivors are dropped off via helicopter in the mountainous wonderland, known as "Riverside Park", tasked with the duty of finding gas and bringing it back so their helicopter can refuel. This beautiful and large forest was once home to park rangers, nature enthusiasts and friendly visitors, but now they're roaming with infected who can't wait to rip out your guts and tear you to shreds. Unfortunately, the survivors entered this area with zero warning as to what is about to become the worst night of their lives... Do you have what it takes to survive?

Zero Warning was a, until now, lost Campaign, republished by yours truly after receiving the rights of ownership from the original map creator. This means that I did not make this map myself, I was simply given the rights to it and publishing is only permitted under my name. Initially I only intended to publish the survival maps, but as the demand for the campaign was there, I decided why not publish that as well?

This is the original campaign from Zero Warning, it's the most recent version and supports only co-op campaign mode due to engine limits regarding Versus. if you'd like to play the survival maps, click here.

Additional Info:

The maps are very big, as is visible by the file size of this Add-on, so lower-end PC's may have issues running this campaign. The maps are purposely designed to be large, confusing and disorienting. The escape helicopter is RNG, this means that it can arrive in 3 different spots after the holdout finale. If you're subscribed to this, as well as the survival pack, both items will conflict with eachother. This is completely normal and doesn't have any effect on the game or gameplay whatsoever.
