Zero-K is a FREE, multiplatform, open-source RTS game. It aims to be dynamic, action-packed and hassle-free, full of clever strategies and constantly moving combat with games lasting an average 20-30 minutes. 


Some of the more prominent features:

  • Epic Scale from tiny fleas to huge mechs and gigantic superweapons that wreak havoc - hundreds or thousands of units on the battlefield, all easily viewable with a fully pannable and zoomable camera.
  •  Realistic Physics mean each shot is physically simulated realtime - you can actually evade bullets if you micro-manage your units! Hills and terrain affect line of sight and radar coverage, and explosions deform the terrain. 
  • Natural Balance allows units to depend on their natural characteristics and the benefits of the simulated environment, not contrived special damages to determine their effectiveness. 
  • Terraforming - change the terrain: walls, ditches, ramps and more, to provide yourself with an extra tactical advantage.
  • Unique Abilities make sure units are fun to use! From jump-jets, gravity turrets, mobile shields, burning napalm, air drops, unit morphs - we've got it all and more! You can even control your units directly in First Person Mode!
  • Streamlined Economy - the economic system is complex without being tedious, with a simple interface and controls. Resources are unlimited and output can be scaled up as the game progresses, allowing for increasingly intense battles. The system is also designed to minimize slippery slope and allow skilled players to make comebacks from losing positions.

Removed many special rules around commander (emp resist, hidden HP etc..)

Many module and weapon rebalanced, most notably:

  • Autorepair 25hp/s -> 20hp/s
  • Fixed Range and Damage adjustments (were cumulative)
  • Fixed Speed changes not stacking, will make many Adv HP actually slow people down
  • Heatray and Sunburst damage nerfs.

Changed EMP system. Paralysis percentage/time will not change when the unit is damaged. Paralysis threashold required to stun a unit is still based on current health.

Infiltrator EMP damage 15000 -> 8000 (as system changed)

Fixed Sumo, Stiletto and Gnat scripts.

Added a widget that allows players to individually configure the starting state of their mobile units through the menu.

Added Team Commends mode as a test, defaults to OFF. When enabled if at any time an ally team has no commander the entire ally team will explode.

Added new award: Share Bear. Share at least 5000 metal worth of units to a teammate and you're eligible to win. However, receiving units from teammates subtracts from your current score.
