Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Over 9000 Zombies! is a game about surviving and battling massive hordes of the undead and the best way to know if the game is on the right track is by player feedback. Guns could be rubbish, excessively powerful or too few in numbers and the players are always the best judges of this. This will allow us to maximize the amount of joy one can take from slaying the crowds of the zombies.”

Approximately how long will this game be in Early Access?

“A few months? This is a hard question to answer as it will depend on the kind of features players want in the game and how long it takes for them to be implemented properly. The current plan would be 2-3 months.”

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

“More stuff. By the time Over 9000 Zombies! exits Early Access it should include things already planned like: more maps, vehicles, expanded multiplayer, plus anything else that people suggest during Early Access. The game currently has lots of room for growth and added depth!”

What is the current state of the Early Access version?

“Over 9000 Zombies! is technically still in Alpha but already has plenty of content to satisfy one's zombie killing desires. Single player is well established, including 20+ weapons, 6 defensive turrets to help battle the unending hordes. Two player online co-op is also in, although this is still very early so you can expect a few bugs with this initially.”

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

“While in Early Access the price will be lower, it's only fair when there might be some bugs along the way. Once out of Early Access the price will go up.”

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

“Ideas, balancing, general improvements, anything to make your zombie killing experience more enjoyable. Over 9000 Zombies! is a game that can expand in various directions and the best way to get the right direction is to listen to the people playing and enjoying the game.”

Update - v0.1.6.22 - Bug Fixes + More!

Over 9000 Zombies! has been updated to version This patch is mostly focused on fixing a few bugs and fully implementing the water tiles for the map editor and Workshop.

  • Water tiles have been fully implemented. Players and land based zombies now suffer a 50% decrease in movement speed while in water. A corresponding animation has been added as well. Zombie ravens, crabs and eyeballs are not affected by the slowing effects.

  • The water tile is now available for selection from the map editor menu.

  • Changed the sound effect for the ZR '86

  • Fixed a bug related to zombies spawning inside of walls.

  • Zombies are now far less likely to spawn near walls, barricades, and turrets.

  • Implemented a possible solution to HUD weapon icons not matching the current weapon selection.

  • A few other minor tweaks and modifications.

NOTE If you encounter a bug where the HUD weapon icons do match your current weapon, please make a post about it in the Discussion Forum. Thanks :)

Mini-Patch: a few tweaks

I made a few small tweaks to the game based on data collected from the prior update.

  • Changed the Kills Per Second achievement "Total Carnage!" to have a requirement of 30 Kps to reflect recent changes in difficulty.

  • Added support for 1280 x 1024 Monitor resolution as requested in the discussion forum. If you have a resolution you would like to see supported, feel free to just ask by making a post about it in the community discussion.

  • Slightly tweaked some values on weapons to make the steps of each tier more balanced and appropriate.

  • Fixed a graphical bug.

  • Lowered the range on basic zombie attacks by about 30%.

About This Game

This is Over 9000 Zombies! the game that uses special mathematical technologies to squeeze the maximum amount of undead chaos out of your PC. Experience top-down arcade action blown out of all reasonable proportions. How long can you survive against the unending zombie swarm?

No precision aiming needed here but you will need a variety of guns! To aid you in your fight against the undead there is a selection of 20+ weapons to enjoy. Burn'em, Shoot'em, Blow'em up, however you prefer to kill your undead, we have just the right solution for your zombie extermination requirements.

Standing around in the open is a good way to die in a zombie apocalypse, which is why you have some options to defend yourself.
Collecting scrap metal from corpses will allow you to build makeshift defensive walls and engineer automated turrets to help you cut down the crowds of zombies.

Sometimes you want to bring a friend along to an apocalypse, right? Well now you can. You and a friend can team up and battle the hordes via the power of the internet in 2 player co-op.
Prefer to play in the safety of your own home, then we have you covered with 4 player local co-op.

Nothing goes better with the sounds of death and guns than a rocking soundtrack, the intense electro-rock soundtrack from Clearside Music will keep you battling through the waves of undead.

As each day and night goes by the hordes of undead increase in numbers, ferocity and variety, who said trying to survive was going to be easy?

Early Access Review
Over 9000 Zombies! is a top-down zombie shooter which is played in a horde-mode style game. The zombie genre has had every last bit of originality drained from it in recent years yet this game somehow feels fresh and is incredibly fun to play. As you kill zombies you unlock new guns and scrap which can be used to purchase turrets and other defences. I haven't had a chance to play much so this is more of a first impressions review but I'm definitely going to play more

+Simple art style which suits the game well
+Nice retro-style visual effects
+Loads of unlockable guns
+Plenty of different turret types to build
+Turrets are very useful when playing singleplayer
+Frequent item drops
+Enemies get different buffs everytime you complete a wave making each wave unique in some way
+You get to level up a skill each wave to make yourself slightly more powerful
+Different types of zombies
+Workshop support for custom maps
+Easy to get into
+With each passing wave the game gets significantly more difficult
+Simple control scheme which is easy to use (KB+M)

-The game only comes with one map (it is only in early access) that is pretty small
-Turrets get destroyed very quickly in later waves
-When a wave begins you are completely surrounded by zombies and this is when you are most at risk from getting damaged


Another great example of why early access is a good thing in some cases and a fun new way to experience that zombie genre many people have come to dislike, myself included.

This game is stale - music's good, but art and sounds are uninspired, weapons don't feel powerful, progression system is primitive, gameplay is slow and repetitive. Not recommended.

Early Access Review
EDIT: Some newbie youtube gameplay:

Good game, there is a lot of fun playing by yourself and going up the days. But, the only con there is, is that their ain't no servers to play with other people. The game would be 10 times better if the game had more servers for other people to play in. Another con is, that the developers haven't done an update for a long amount of time and that worries if i bought the game too late.

Just finished playing 2 hours straight without even noticing :D Very enjoyable game. In my last run through i made it to day 9 which i found very challenging to do. On the game mechanics; I enjoy the turrets and building yourself a little base, however i didn't "feel" much difference between the range of weapons you can use. In the end i mainly ended up relying on my turrets and just throwing out my grenades, which i had over 300 of. The grenades thing i feel was a bit ridiculous as that is far more the you should be able to collect, and i was pretty much spamming them constantly. Other then that a very enjoyable game, and i hope i can make it to the 20 day mark :D

(I Streamed my first playing it, however it isn't on the twitch game list so only 1 person actually saw it in the whole 2 hours :D. If you're interested the recording can be found here for the next 2 weeks at least:

Early Access Review
It's not bad if you're playing to reach Day 10, after that it just becomes an (easy) grind-fest. I made it to day 27 (12th place on the leaderboards for kicks) before I gave up. Once you get a powerful enough weapon, you can just stand there and hold the mouse button while using your other hand to feed your mouth with chips.

I can see this game getting a lot better, but:

Nays (as of now):
- I found very little use for most of the weapons, there's a lot, but you'll probably never use them.
- Items that give you temporary stat bonuses don't last long enough/aren't very interesting, I couldn't justify picking them up.
- Block placement is fun, but I never seemed to be able to collect enough resources to build more than 8 blocks at a time.
- Music starts to get annoying, it's not a bad track, I just wish there was more than NUNUNUNUneeeNUNUeeeeeNUNU...
- You can't be bothered to look at the UI early on, it's very small and should be more noticeable.
- The cursor/crosshair is also difficult to spot, I never know where it is after blinking.

- The A.I works very well, I can see there is some AGGRO involved.
- Bullets don't simply go straight, there's some realism.
- Hit testing is spot on for walls/structures.
- Various mobs, the game is not limited to zombies.
- I don't regret paying $4 for this.

Basically, this is Bird's Eye Serious Sam, but the weapons will eventually need some major balancing.

- Map Maker, especially for a tile-based game like this.
- More items: fences, mines, det-bombs, bla bla.
- Bosses, bosses that don't like it when I spend that past 3 hours camping in my 7x7 structure.
- Leveling and more stats... Make this game better than Diablo 3!

Early Access Review
There once was a series of flash games called "Endless Zombie Rampage". It was a simple game, consisting of shooting zombies in a parking lot. The weapons got better, the zombies got harder, and it was fun.

But it stopped, and that wasn't good.

Now, a successor has arisen, and it's called "Over 9,000 zombies". Weapons, turrets, walls, thousands of zombies to kill, an expansive map, far surpassing it's predecessor.
But unlike EZR, this game never stops.

In EZR, you got a breather. A chance to go to the store, go to bed or go back fighting, but it was a break in the day.
In Over 9,000 zombies, your only solace is death. You get a minute between waves, where zombies no longer spawn, then it's back to the frantic shooting, dodging, and repairing that is O9Z.

And I for one, wouldn't have it any other way.

A very fun and addicting top-down zombie shooter. This game is fantastic in Co-op. Many different weapons to use, different zombie types, different turrents to place to defend your position, and more to come since it's in Early Access. Also the soundtrack is freaking epic. I have high hopes that this game will turn out even better with more content and maybe more modes to play? Either way, very awesome game that I reccomend to any zombie shooter gamer. Worth the price in my opinion.

Edit: Also the Developer(s) are very kind and helpful for any questions I had and responded to me directly with more help than I expected! :) Thank you again Loren!

This game is really intense and good. It's a lot of fun and I can only see it getting better. At the time of this review I have not played with any friends but I can only imagine that it makes the experience better.

Good retro graphics, a nice soundtrack, retro sound effects make this game a must have for the retro gamer. If you like top down shooters then pick this up, you won't regret it.

At the time of this review as far as I can tell there is only one map, which is kinda bummer, but devs plan on adding more plus they plan on adding steamworks support so players can make their own maps.

Early Access Review
Update 25 November 2014:

I've had to change the review to a thumbs down due to the latest updates to the game:

The good part of recent updates was that they removed the guns being unlocked permanently feature and they are now unlocked each time you play as you would expect in a permadeath game like this.

The bad part of the update is what they did to the map: It used to be a fairly large, varied map with multiple buildings, water and so on; now it's just one tiny map featuring one building and there's no water.

This is something that happens with early access games sometimes and I really don't like it. Valve say that you should be careful with EA and only buy games if you want to play them as they are now. Well now you can't even bank on things staying the way they are when you buy the game: they can get worse, as is the case here.

Some of the videos on the store page still show the old map which is very misleading for new customers. The videos have always been misleading in other ways too: showing glitchy video effects that are not present in the game, despite in some cases appearing to be. Also at least one of the videos rotates the screen but you can't rotate the screen in the game, they are actually rotating the picture to give this misleading impression.

edit: The dev has said the large map won't be coming back:

"We had to make some design decisions about the size of the map, mostly because the sort of zombie survival game that this is, is the sort where you barricade yourself in a build and fight off an overwhelming swarm. Both a large and small map were tested, but because of the spawn mechanics and the way the swarm operates, I had to choose either a small one or a larger one, and the small one just played better in my opinion."

Pretty fun retro-style zombie shooter. Killing off hundreds of zombies at any given time, collecting different weapons, power-ups and scrap metal used to make turrets and fortifications and some challenging gameplay make this a fun time.

The title is no exaggeration. There's a lot of zombie carnage to be found here that will keep you entertained for hours. It's odd, because it's another zombie game, but for some reason, this one just appeals to me. I think it's because it takes little thought to play it. It's hard to explain. The point is, this game is awesome, and you should get it.

Early Access Review
Early Access games come in all manner of different states. I would say this one is in a perfect place to be entering Early Access. The game itself is already playable and fun, but I can still see where they can add even more in the future. The co-op works flawlessly, you don't have to jump through any hoops to play with a friend. I ran into very few bugs while playing and none of them were game breaking.

Over 9000 Zombies! is a Tower Defense like game, where the thing you're defending, in essence is yourself. You can place turrets, of which there are currently 6 to choose from, you can place a block barricade, and there are roughly 20 weapons to collect. Zombies drop health, grenades, scrap (with which to build), and on the rare occasion, new weapons.

I played only co-op, but I can see it being a little difficult for someone in single player. After one play through, we found ourselves searching for a more defensible building, as well as working out strategies to survive specific zombies on later, tougher days.

I look forward to future updates. I hope to see more turret types, more maps, a map editor, perhaps more zombie types and more zombie 'bosses'.

Overall, I highly recommend it!

Over 9000 Zombies is a top down 2D shooter that is in development, and what was given to us on day one was great in my opinion, it is simple, it's easy to get into. Alot like Nation Red without the absurdly overwhelming difficulty to start out on. You collect scrap that zombies drop to fortify where you wish to dig in at, you can also build turrents and find new weaponry that zombies may drop. There are also an absurd ammount of zombies on screen at one time, there is veriations of zombies among the horde that don't feel so rehashed. A massive assortment of weapons that you can pick up that carry from game to game to make you stronger aginst the zombie threat plus new weapons to pick up ontop of that.

It is still quite in development, but I don't think it needs the early acess logo, it is solid enough to play on its own and cheap enough to afford, from what I see currently a great game is only going to get better, pop for it if you can afford it!

Also I would like to note that the devloper of the game, is listening to those who comment on it in the forums. They enjoy ideas and are looking to give the fans what they want to make a great game fantastic. Most developers really don't do this.
