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!”

Happy Halloween! Alpha 1.14 is here, and this latest update means more zombie chaos coming your way from Dimension Z. Tuning passes for Mission03 and Skirmish01, and a whole new Skirmish02 map lead the way, but new art, new sounds, new hotkeys, a new destructible, gameplay improvements and a bunch of squashed bugs round out the patch.

Undead Overlord is also part of the Steam Halloween sale, and the game is 15% off for the weekend. That means now is a great time to pick up a copy or infect, er, that is - tell that zombie-wannabe friend!

Still on the roadmap coming up we’ve got new missions, a more powerful sandbox mode, engine upgrades, and more meat sacks to munch! We hope you enjoy, and as always, thanks for being on this Early Access ride alongside us.

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.

The pace of development on this game says it all. As of now (2/16/15), the last update that's been made was well over two months ago. Gameplay is glitchy, unresposive and all-around not appealing. Heavily regret purchasing.

Early Access Review
I've waited for this game to come out for a long time, and when I got it I thought it was cool at first... But quickly after beating the first mission, I got bored very quickly, with some rage on the side because the humans are ridiculously powerful with shotguns. Updates happen every 2-3 months, that's right, no matter how minor they are, a sound fix or something small added into it, the update will take over 2 months to come out, for reasons I do not know.

I very deeply regret buying this, for now.


It has been nearly 4 months now as of March 27th, 2015, the last update was in December of 2014, I feel as though as the developers have either abandoned Undead Overlord, or are extremely lazy.

Its a good game with modest goals, but severe lack of updates gives it a feeling that it will never be finished. I enjoy the game for what it is, but I think the money i spent on this game will not be worth it in the end. Get this game if you just want an RTS with 3 missions and 2 skirmish maps, for it will never be done and your money wasted.

it would be good for an "early access MOBILE GAME" but for so little content, few and far between updates, it doesnt fit its price tag, granted its a small dev team but at least SOME posts keeping us in the loop of whats going on would have made me feel better knowing that something would be done, its starting to feel like another one of those early access cash grabs. still for what its worth its a fun game, if it was mobile you could complete it before you even finish a poop.

Early Access Review
*Early Access impressions, Subject to changes

Very fresh and innovative ideas of being the ruler of an army of zombies.

The game does not have a story as of yet because its mindless atm, but there are 3 missions+ one rogue-like skirmish level where the layout is the same but the units arent. that you can play, at first glance the game seems like a simple drag a box around your army and click them to kill other humans but then strategy comes in when those humans starts wielding weapons and thats when you'll have to start thinking and using power kills.

The gameplay is an rts style game with very easy and basic commands to use. There aren't many hotkeys implemented yet but you can group up an army of zombies and strategically send them after humans, then the humans starts calling in cops, rednecks with guns, and the military. The early release is just a taste of things to come. Later on in the game as you killl more people the brain/blood meter left goes up and you'll be able to combine zombies into speed zombies, tank zombies and the brain zombie, THE BRAIN. While you are wrecking havoc the game also offers destructable environment which is really nice. Hopefully we'll see more of that in the game and a multiplayer!

+ Overlord of zombies rts style game, control army of zombies to destroy humans, haven't seen anything similar since stubbs
+ Simple interface easy to use
+ Upgradeable zombie units
+ The radio in the menu gives you an insight of what is going on in the town while you wreck havoc, gives the feeling of immersion

* What would be nice to see or what isn't available yet*
- Not much hotkeys yet
- Only the skirmish is randomized and rogue-like, Hopefully we'll see everything else the same
- Graphics is decent but if you play RTS for graphics you are playing this game for the wrong reasons
- Zombie ai pathing can glitch out sometimes
- Multiplayer hopefully with your supports!
- more destructables
- voice overs are nice hopefully more radio work
- The rest of the maps! hopefully set in good location and procedurally generated content would be nice.

Early Access Review
It's got potential. If only we could do something about the shotguns one-shotting Zombies, it would be a wonderful game.

I like the fact that clearly, the missions are meant to have some challenge to them; sacrificing individuals to kill stronger enemies, luring enemies out, using the arch-types effectively is a MUST.
I also like the fact that the arch-types reanimate their foes, it's nice to know that when my Speed Zombie is cutting a swath of death through SWAT soldiers, it's fallen prey will revive and help continue the fight.
I /LOVE/ the fact that the Humans retain their appearance they had when alive, as Zombies, rather than relying on a single model.

However, I have a few problems with the game:

AI: I dislike how the Zombies act like foolhardy lemmings and just all charge a nearby enemy without me saying so, it's a pain in the ♥♥♥ to try and keep them from rushing out of cover and being mowed down accordingly, it's also a pain to get a large group through a door in a timely manner.

Weapon Balancing: Shotguns are more powerful at range than Assault Rifles. WAT. I'd understand if it's like, a one-hit up close, but the range of shotguns is just annoying as all hell.

But, overall, it is a game with potential, and while it has problems, it's considerabley better than most other Indy strategy games, and I look foward to tracking this as it updates accordingly.

Early Access Review
Full disclosure: review copy provided by developer/publisher!

I'm going to preface this review with what I think Early Access should mean. Then I'm going to tell you what "Undead Overlord" is. Early Access should be a title that, while unpolished and lacking features, is a fun experience that feels... nearly complete. Like a game that can stand on its own with maybe a little asterisk. And throughout its developmental process it should only improve, getting polished and expanded. Good examples of this are "Kerbal Space Program," "Sunless Sea," "Prison Architect..." the list goes on. Then they're released into the full-release wild, like "Betrayer" and "Sir, You are Being Hunted."

That is the expected and desired life cycle of all things Early Access. And let me add this: I think Early Access is not above criticism - even downright damnation. If a game is bad, it's bad. I'm not giving it leeway because "it isn't done yet." If you're selling a product, finished or not, I'm going to criticize it. People think criticizing Early Access is tantamount to punching a baby. I don't agree with that. Especially when the game is 30 minutes of content with an intended additional 60 minutes of content.

This game is bad. Objectively. It is a fact, like how old the universe is, how its heat death is inevitable, and how St. Paul, Minnesota is the happiest place on Earth (full disclosure: I've never been to St. Paul, Minnesota). Firstly let's address the graphics, arguably the least important feature (especially for an RTS). I feel that you have three options when developing a game: you can go the technically impressive route, the artistic route, or a wonderful fusion of both. "Undead Overlord" decided on the fourth, controversial option of terrible. This is pretty ugly. There is no artistic merit here. This is not fun to look at. This is like staring at the sun; it will cause inevitable blindness, madness, and is wholly inadvisable. It is jagged, blocky, muted, and utterly painful to look at. The levels are barren (particularly the one skirmish level). The character models look like the tourists in a "RollerCoaster Tycoon" game. I know graphics aren't that important at the end of the day, but you still have to stare at this for hours on end.

Gameplay is the real meat of any good game sandwich. Unfortunately for you, "Undead Overlord" features a single, suspicious slice of green bologna. You select your zombie, click on a target, and he runs over to jankily smack him or her around until they collapse into a pool of blood, resurrecting to join your dead ensemble or providing a snack for health and strength. Interesting concept, yes. But it's shallow and not fun. You're just clicking your increasingly unruly horde at dwindling townspeople and first responders until there's nothing left. Then you're on to the next of three levels. You'll blast through these in... five, ten minutes (the levels are small and same-y)? But don't worry, the developers plan on adding six more! That's roughly an hour and a half of entertainment potentially! And if they meet some unspecified monetary goal they're going to add such exciting features as MULTIPLAYER, HUMAN CAMPAIGN, and MAP EDITOR.

The AI is nonexistent. They react to your presence (sometimes) but don't expect them to seek you out or patrol of their own volition. This is a very one-sided RTS. The aforementioned skirmish level really shines a light on this. The level design on the single skirmish level is also pretty bland, featuring nothing but room after room stuffed with an assortment of humans and/or dog corpses.

So that's it. That's "Undead Overlord." It feels and plays like an iOS game. The trailer is admittedly cool looking, as is the concept. But I didn't see that game when I played. I'm not picking on this game or the developers. I just don't want you to be burned. This is not worth your hard-earned cash or time. When you can buy complete games for less than this, and when you can purchase Early Access titles more polished than this, what's the incentive? Do you like to gamble? To live dangerously? "Undead Overlord" is about as fun as staring into the sun. Some might disagree, shouting in disbelief while staring till their eyes melt out of their skulls. But you and me? We'll just keep walking, sunglasses on and eyes fixed squarely ahead.

This game can be great. Instead of killing zombies you controll them witch is fun and you don't see many games that do this.
Its in alpha but shows a lot of potential to become a great game. I'm hoping for new levels to come as soon as possible.

Obviously there was some stuff that i didn't like. Such as the way the zombies behave. For example when you tell them to attack someone even tough they are getting their ♥♥♥ kicked they completely ignore the person thats tryng to kill them. So pretty much what you do in this game is to tell them where to go and they handle the rest. The heart beat when your chaos meter gets filled up is really loud and annoying... So on. I am writing these of the top of my head so i probably will froget about some of them.

Played all the current levels. First 3 was a blast to play. Skirmish map however is really really hard.
The last map is only for alpha players and it basicly lets you spawn any npc you want and just do as you please witch was the best map for me. I dont think there will be anything like a map editor/creator. At least i havent heard of it. If there is and i think there HAS TO BE a map editor. That would give the game so much replay value.

So AI acts stupid sometimes. Both zombies and humans. Haven't come across any bugs. The existing levels are pretty good but there is room for improvement. Other than that this game is really fun to play and it has an idea that we don't see in games very often. I cant say you will like the game but i certinly love zombie games and this was one of the best i played as far as the gameplay goes...

There are hundreds upon thousands of zombie survival simulators out there, but this one let's the user assume the role of the other side for once. No longer must you cower in fear in some corner, starving to death because you're afraid to go outside. As the "undead overlord", you'll control swarms of zombie units with intent on creating mass destruction. It's currently a single player game with limited functionality and bugs (as one would expect from an Alpha build), though the developer did mention multiplayer, a human campaign, and map editor as "stretch goals"...meaning these features will be added IF they receive enough support.

I'll be interested to see what direction this particular game takes during the Early Access stage.

Well, before I tell you what Undead Overlord is, let us first cover the basics of what it is not. It's not finished for one thing. A second key point that is worth mentioning is that it is not a game with femiliar gameplay. Both these 2 things are being said not in a negitive sense, not at all. They are just worth being noted before i go into what the game is.

Undead Overlord, I saw this awhile back on Kickstarter. The concept of being the zombie-leader-commander was a very good hook, and still is. The game never made it to being fully funded. But now its been out for early access, which is cool. Gameplay is unique a bit clunky on a few things, but taking into account the game isn't finished yet should put some minds at ease for the time being. The game plays like a RTS but most of the time I feel like i'm always starting out with a infantry-flood tactic, which I suppose is to be expected (because you're zombies). All things considered, the game does show alot of promise, weather it can get rolling is up to funding and a whole lot of drive to see this through to the end.

So far so good. The basics are there. It needs some work, like adjustable difficulty, minimap, moving the camera to the selected zombie when you click on their icon. Too bad the Capcha on their forums account creation isn't working.

This game holds a nice touch of a unique genre. The graphics may not be great and the game only has 3 missions and 1 skirmish, as well as a sandbox style map. But for an early access game this isn't bad compared to some of the other things on greenlight. But think it through before you by the game. Were you really expecting a whole 10 levels and HD quality graphics? Those are pretty rare on greenlight.
