What the developers have to say:

Why Early Access?

Gnnarrrghh! K-Krra-reck-k-chack-k . . . Welcome, human meat-sacks!
The Undead Overlord welcomes you to Early Access! You are amongst the proud meat-sacks who will help the Overlord grow through the offering of your brains. Yes, those juicy tasty brains of yours are just what we need to feed ourselves, er, that is, to feed our . . . um . . . to help us finish our game! Yes - that’s it! To help us with feedback and testing and most of all inspiration. Become a part of our horde and help us bring you a better game - we can't do it without you and your tender, succulent, delicious, oozing brains!”

Approximately how long will this game be in Early Access?

“The game may be in Early Access for quite some time. That will mostly depend on whether the game’s player community grows large enough to justify the addition of stretch goals, but also on the lives and fortunes of the game’s team of developers. Our goal is to reach a final release state for the game no later than one year after its release on Early Access.

In the end, though, it will be done when it’s done. We want to bring the game to you as quickly as we can, but we are still only human (not yet having achieved interdimensional transcendence ourselves).”

How is the full version planned to differ from the Early Access version?

“Again, this will depend on which additional features are added along the way. In general, though, we intend that the Early Access version will steadily receive additional features and content as we work on it, so that the later stages of Early Access, immediately prior to the game’s transition to Released, will strongly resemble the final product. See the Planned Features list in the Game Description for more info.”

What is the current state of the Early Access version?

“We are at Alpha1 for the start of our Early Access. Moment-to-moment game play is at ~80% feature complete, though still in need of a lot of tuning. Most major features are at a second pass stage, but there is still plenty to be done before they are fully polished. See the Current Features list under the Game Description for more info.”

Will the game be priced differently during and after Early Access?

“Yes, the Early Access price of $14.99US is a 25% reduction from the intended full price of $19.99US.”

How are you planning on involving the Community in your development process?

“We’ll monitor the community on Steam and elsewhere . . . and we’ll read every single message we get. We can’t guarantee a response to every comment, but we’ll do our very best to answer any and all questions, and we’ll take all suggestions and ideas into serious consideration. And, of course, we’ll be very thankful for any bug reports that we get from the community!”

October 29


The Alpha 1.16 patch is finally here! We’re excited to add two new missions to the game, a new and dangerous human weapon type: the machine gun turret, and a whole new section of the Mission Select screen to make room for the new missions. The usual complement of bug fixes and smaller improvements, as well.

Mission04 (“Night Terrors”) is our first nighttime mission, and takes place in the Small Town map, after the initial outbreak, when the human military first confronts your growing zombie infestation. The boots of heavily armed soldiers echo through the shadows, pools of light emanate from street lamps and spill from the brightly lit shop windows. Some citizens seem to be easy prey, but many are now armed. Hey, what zombie doesn't enjoy the night?

Mission05 (“Breakthrough”) introduces the Tank Zombie to the story, as well as a new destructible that requires the use of a Tank Zombie to successfully complete the mission (we’ll leave it up to you to discover that particular destructible). Okay, actually, it is possible to brute force your way through the mission without taking advantage of the new destructible, but it’s waaaay harder, and not really recommended. This is the first mission map to use the Warehouse District set of graphics, much of which will be familiar to those who have already played the skirmish maps. The Warehouse District maps are neither night nor day, but instead are set in a kind of eternal post-apocalyptic gloom - the kind of thing that drives human survivors slowly insane for lack of a proper day/night cycle.

Full patch details are here.

About This Game

"Danger, Will Robinson!"
Filled with bugs, shorter than you want it to be, lacking features you crave, and just *not* fully tuned yet - this alpha release may infect your brain and leave you curled, twitching in a corner, while you jones for more zombie goodness. Play at your own risk!

That having been said . . .

Raw, aggressive hunger - there's nothing like being a Zombie when you want to do some damage! Now you can control your own horde of zombies and lay waste to the tidy world that humans have created for themselves. Feast on their brains, grow, mutate, and gain incredible powers. Take over a small town (deputies are delicious!). Overwhelm the arriving SWAT units, gather civilian bodies, and reduce a mighty city to rubble. Feast on the remains of generals as their weapons lie smoldering and scattered.

Undead Overlord is the world's most succulent Zombie Dominion RTS. Zoom into a world where destruction is the goal. Mindless zombies? Not when you are the controlling Mind!

We’re proud to make our Alpha1 build available on Steam Early Access. The game was approved for distribution on Steam through the Greenlight program last fall, after just over a month’s worth of voting, but the game still needed more work at that point. The fact of the matter is - it *still* needs more work!

You all know about Beta software. Well . . . Alpha comes before Beta, so it's full of crawling bugs and creeping inconsistencies that we haven't had time to stomp out just yet - but you can help us do the stomping, and have some fun in the process!

Alpha1.16 lets you experience the beginnings of the reign of the Undead Overlord with the first five story missions, two skirmish maps, and a special alphaTest map available to those who take part in the game’s Early Access program. Play the game like you're riding a bucking bronco - ride that sucker into submission. Then participate in forum discussions on the current state of the game, have your say, and join us as we add more missions, more maps, new features, and work towards a full release.

Early Access Review
So disappointed with the devs. The game had so much potential but they just abandoned the game and ran off with the money.

Early Access Review
I loved the game. it seems the Devs. are running behind on it, which i hate... its a good idea of a game to put you in control of a horde of zombies instead of blasting away at them like every other game now-a-days... but i'm with the group when this game is dead and the creators just took the money... It's sad.... i just wish people would stick to their creation and complete it instead of putting it on early access just to get money out of gamers...thats f*cked up. there is no decency in indie devs anymore. they take advantage of gamers who like to play cool looking games. tisk tisk...

Early Access Review
Really disappointed in this. It seemed so promising.
No updates at all, just a few levels filled with bugs, the devs better get their heads outta their as'ses for real.
Some people actually paid money for this, and they expect something in return.

The game is dead, no more updates no more zombies, no more anything. Wish the steam refunds would allow return of product if it isnt finished in a timely manner have a feeling Devs would be more inclined to finish products if their money could be lost.
