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!”

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 lets you experience the beginnings of the reign of the Undead Overlord with the first three story missions, a skirmish map, 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
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.

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.

Early Access Review
The game is abysmally slow devlopment wise and it could be safe to assume that the team behind it might have abandoned it.

Early Access Review
Basic concept and premise are great. Ground Zero for a zombie infestation? Awesome!

However, game is Dead, No updates since last year. no communication until June of this year and nothing since then. Game hasent changed, no new maps, no new characters, no new systems, no new updates, no new information, no roadmap nothing.

At least with Steams refund policy you can see for yourself, then promptly refund unlike those of us who supported the game from the start.

Early Access Review
The game is a perfect example of the risk associated with Early access. Devs took everybodies money and ran off with it. No updates or communication in over a year. Sadly, a really interesting concept gone to complete waste. DO NOT BUY!
