Compete with other players to be the most insane Spine Crawler master! Move your Spawner to create Spine Crawlers. If all of your Spine Crawlers are destroyed before you can spawn new ones, you lose. Eliminate all other Spawners or reach 750 kills to win.
Kills award you with special units or abilities to help you claim victory. You can also upgrade your Spine Crawlers in various ways to gain an edge over the competition - including elemental upgrades, with their own strengths and weaknesses.
