What is it

Swarmtide is a single-player real-time strategy game set on a colony world the Swarm has already overrun. You land with a handful of people, and keeping them fed, powered and housed is what the whole economy runs on. Build out from the landing site, wall the colony in and lead your soldiers and walkers against waves that come back bigger each time, until a final assault of about 50,000 creatures hits your walls. Your units go where you send them, when you send them.
