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.”

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: v0.1.5.0 - Tons of Changes!

September 15

Over 9000 Zombies! is going to see a few fundamental changes in this patch as well as new content. The immediate changes players will see are those to the map. The world map is now much more concentrated and will focus on the player defending a particular structure. This leads to other design changes related to the mechanics of the map as well. For instance, given sufficient time, the structures themselves can now be completely torn down by the horde of zombies. The player will also find that it is their responsibility to create barricades to keep zombies from wreaking havoc on their gun positions and portions of the structure. Players will have to keep exits clear should the need arise to abandon their position, since player created structures now act as barriers for both the player and the zombies. The map is more focused and concentrated, so zombies now spawn outside the bounds of the compound as opposed to scattered around the players location.

In between the waves of zombies players will discover that they are allowed to upgrade one of four select attributes to aid them in their zombie slaying. The first is Durability, which will increase the player’s maximum hit points as well as regenerate a small amount of health points regularly over time. Durability is key to staying alive for as many days as possible and can be critical to recovering hit points when trapped by the zombie horde. The attribute Carnage, will increase the players damage as well as lower their reload time. Carnage’s effects will especially be noticeable on certain guns where the reload time is the main bottleneck to dishing out damage. Such is the case for the shotgun, M-16 and grenade launchers for example. Resourcefulness increases the players ability to salvage scrap metal, increases the hitpoints recovered from health packs and increase the number of grenades collected. This will allow the player to construct a fortified base much more quickly, receive a large cache of hit points from key health pickups and keep their grenade habit well fed. The final attribute is Engineering, which upgrades the player constructed turret’s rate of fire and their damage. As the zombie horde grows larger, players will become more reliant on their turrets to dish out more damage, so investing in engineering will prove useful to survival.

Players will also discover some new content as well as various other changes. They will find a new Damage Per Second and Kills Per Second visual meter on their screen as well as some associated Steam Achievements. To aid the player in their survival three new constructible turrets have been added, including a rail gun, a white phosphorous launcher and a plasma projector. Turrets also now emit their own source of light so they do not get misplaced and lost in the dark. There have also been various balancing related changes made across the board, some visual improvements and several bug fixes.

Full change log:

  • New attribute system!
  • 4 new achievements
  • KPS / DPS Meter
  • New Turret: Rail gun turret!
  • New Turret: Plasma Projector Turret!
  • New Turret: White Phosphorous launcher!
  • Changed the stats on various weapons to adjust for balance
  • Turrets now act as their own light source
  • Players are no longer able to walk through player constructed turrets and walls.
  • Zombies now spawn off the map as opposed to randomly around the players
  • The maps starting environments walls are changed in design and size. They are also all now vulnerable to zombie attacks
  • Improved animations on Zombie Ravens.
  • Changed item indicator rings
  • Changed Fire spitting zombies to fire just 1 fireball at a time.
  • Adjust Zombie counts on various days and zombie hp to adjust for difficulty.
  • Flame throwers and Flame Turrets now have increased base damage and slightly increased rate of fire.
  • The save/load game feature has been phased out.
  • Ambient objects are no longer just randomly spread about the map
  • A new smaller, but more focused and dynamic map has been implemented.
  • Floating combat text has changed in scale and color to make damage more visible.
  • Some minor changes in sound design
  • Turrets have improved Line of Sight detection
  • Various bug fixes, including collecting items after death, broken counters, etc
  • Map editor coming soon!

If you discover any new bugs please make a post about it in the game's discussion forum. Also feel free to share your thoughts on the new update!

Patch - Four Player Local Coop!

July 16

Patch Notes - Local Cooperative play!

  • 4 Player Local cooperative play has been added! Features a new build interface and more.

  • Globably lowered volumes and adjusted levels to make sound more controllable for varying audio set ups.
  • Fixed some sound effect issues where volumes on certain sounds weren't being properly adjusted according to the options.
  • Fixed an issue where quitting to the main menu immediately started a new game
  • Fixed some other miscellaneous issues with menus
  • Improved some network performance issues

    Local cooperative play now allows you and up to 3 other friends (4 players total) to play Over 9000 Zombies! using Xbox game-pads. The game plays similarly to a multiplayer game. Players respawn after a given amount of time after dying and if all players are simultaneously dead, then it is officially game over and a new game will start. Resources are shared among players, otherwise it would be optimal for a single player to do all the collecting of scrap metal. This way all players that seize an opportunity to collect items benefit each other. Weapon unlocks are still individually acquired. Power-ups when collected, power up your entire squad.

    If you encounter any issues or bugs please feel free to post them in the game's discussion forum! All suggestions are welcome as well:

About the 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
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!

Early Access Review
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.

Early Access Review
While not quite a review, here is an overview and first impressions video. This was recorded 3-4 hours before officially going on Early Access.

In it you collect scrap metal, grenades, health, and new weapons from fallen zombies and enemies. You can use the scrap metal to build turrets and barricades to try and survive the hordes of thousands of zombies. It actually seems to work quite well, though right now it does have a few good and bad points.

-Surprising amount of content so far.
-Music is nice and has good production value, gives good energy to the fights.
-Vast numbers of enemies and explosions going on. Tons of carnage in later days.

-The Map needs more variety or randomness, right now they are just a few main areas that just work flat out better than others.
-The difficulty curve can be unforgiving if you don't plan.
-Maps needs some sort of tile smoothering or filtering to make it feel less sharp.

Those are just some of my thoughts, so far it plays nice and actually pretty fun. It's certainly quite full for an early access game these days.


Edit: I had said that the grenade launcher stops working. What I didn't think about was it using actual normal grenades as ammo, and it appears to use one grenade for a full magazine. So thats not a bug.

Early Access Review
I've played a whole lot of zombie survival games, so it's rare that I see anything new in these sorts of games that I haven't already seen dozens of times. Over 9000 Zombies doesn't really bring anything new to the table, but its straight-talking no-frills approach to the genre is laudable. You're plopped down in the middle of the hordes, and told to shoot and build your way to victory. There's a bit of tower defense going on too, through which you can put together a base to keep the undead back, and then hope for the best. My video playthrough can be found here: http://youtu.be/yDSJuETo3gA
