Development Update - April 2017
  • Added Circuit AI to our install and update system. Our AI community has made a few good AIs and we've selected Circuit AI to include by default. Circuit has difficulty levels and replaces the fairly stupid inbuilt AI written several years ago.
  • Produced two good, basic, tutorials. There are plans for a third.
  • Added a streamlined skirmish menu. Make a few selections and instantly start a game without the daunting task of full game customization.
  • Implemented a campaign framework:

On the multiplayer front we've added party support to matchmaking (for 2v2 to 4v4), added coop, and given it all a thorough testing. We have also run a few small planetwars rounds since people love multiplayer metagames so it would be a great feature for release. We found a few bugs and balance issues in the last round but we're confident that they are fixable for release. It was still a lot of fun.

As always, we've spent a lot of time tweaking and polishing the game itself. A notable milestone is that we finally made a proper skin for the UI elements and polished their layout.

Development Update - October 2016
  • The addition of projectile glow with deferred rendering.
  • Remodels for some of our more dated units.
  • A unique constructor for the gunship factory.
  • Improved start positions - not just rectangles.
  • Improved interface for terraforming.
  • Dynamic commander upgrading.
as well as the usual bugfixing, balancing and miscellaneous improvements. Most of the changes are over three months old because, frankly, developing the game itself is the most fun. Our focus on other parts of Zero-K is partially because they were lagging behind but also so we can get the relatively boring bits out of the way. We seem to be on track to do just that.

Release date: 2010
Zero-K is a free, multiplatform, open-source RTS game where opposing Commanders wage war with increasingly large robotic armies. With design and balance refined over many years of development Zero-K offers many interesting strategies and ways to play.
  • Start with a single commander, build large armies and test your strategies.
  • Enjoy endless variety of tactics and strategies with over 100 units and 3000 hand-crafted maps.
  • Let the powerful interface and unit intelligence help you control large armies while leaving room for smart micromanagement.
  • Change the shape of the battlefield with deformable terrain and terraforming.
  • Join our community of smart, friendly players with ladders, campaigns and tournaments.

Zero-K boasts over 100 diverse units including Vehicles, Tanks, Hovercraft, Planes, Gunships, Ships, Spiders and giant Striders. The amount of unit diversity really is extreme; from the well armored Jack beating your units to death with a spear to glass cannon saturation artillery. Add this to special abilities such as cloaking, terraforming, jetpacks and EMP warfare and there is plenty of room for innovative strategies.

We are dead set against tedious micromanagement. A lot of work has been dedicated to make implementing a plan about as complicated as the plan itself. Other games may limit your ability to implement simple plans such as "move to stand in an arc" or "engage the enemy and stay at your maximum range" but Zero-K has smarter units than that. That is not to say that Zero-K plays itself, far from it, you just won't have to click frantically to make your armies understand simple concepts. Fight your opponent, not the interface!

Units are balanced intuitively using physics. Your robots are armed with many weapon types; Lasers, Missiles, Lightning, Plasma to name a few. These weapons have different characteristics, some are slow and inaccurate while others travel as fast as light. These physical characteristics are used to give units a readily understandable role, for example the small speedy Glaive excels at dodging slow missiles. There are no armor tables to memorize here.

This game has been designed with 1v1, Teamgames and Free For All in mind as well as skirmish AI and cooperative Chicken Defense (alien invasion). So whether you are looking for intense competitive play or more laid back epic battles there is something for you. For competitive players Zero-K offers 15-20 minute long intense battles with very little messing about at the start. Other players may prefer a small tactical teamgame or a larger slugfest where economies can ramp up to produce battles of epic scale. Free for all gameplay actually works quite well with many ridiculously expensive superweapons to create tension and break stalemates. Development of a singleplayer campaign is underway and there are currently some stand alone missions to play.
