On May 15 2019, The Culling servers will be taken offline permanently. After The Culling 2's disastrous failure, and eventual removal from storefronts, the original game was updated to a free-to-play game under "The Culling: Origins".
On March 18 2019, a announcement was made that all online features of the game will be pulled, after in-app purchases couldn't generate enough revenue.
The game and it's microtransactions will be made unavailable shortly from storefronts, however those that still have the game can use the offline features.
