About This Game

OMG! Alert! Alert! The City of Redfield has been hit by an outbreak of exploding zombies! For cool and unimportant reasons these suckers literally explode when shot, showering their zombie brethren with gore and causing chain reactions of showering zombie gibs with just a single bullet!
As a lone cop armed only with bare wit, a large-calibre sniper rifle and bullets coated in a zombie-exploding pathogen, you are the last man standing at the epicentre of a zombie outbreak. Your mission? To succeed where the police and army failed by clearing the streets of 8 different strains of bloodthirsty zombies and stop Armageddon in its tracks!

Use your sharpshooting skills to vanquish 100 branching levels of zombie hell across 40 unique environments in this hugely addictive chain reaction shooter. Earn 400 shiny medals and cold hard cash to buy 100 different upgrades, all designed to MAKE THOSE ZOMBIES EXPLODE!

OMG Zombies is an awesome reimagining of a genuine classic: the critically acclaimed OMG-Z, a top-ten all-time Metacritic rated PSP game and ranked as Metacritic’s best action title ever released on PSP! The guys at Push Square gave it 89% and called it “a must buy” game, Escape Rope claimed it’s “ of the best zombie games in recent memory” and Defunct Games gave it an A rating saying it’s “so addictive... I still can't get enough of watching the explosive chain reaction caused from a well-placed bullet.”

Now the new and improved OMG Zombies features completely redrawn HD graphics, more gore, more levels, more upgrades and all-new content including 12 trophies, 100+ leaderboards, a 20-stage ‘Prestige’ system and 5 beautifully illustrated endings.

Nope. Don't buy it.

A clone of the Flash game-series Infectonator, but does nothing better or even as good as Infectonator. Sadly a huge disappointment as a game.

The comic strips explaining the story are lovely, very nice art style.

The main problem with it, aside from the poor amount of gameplay, is that it's an obvious tablet game not made for a desktop computer. The developers really need to redesign or at the very least resize the UI and other elements to fit for a desktop game.

Barely worth the $2 I paid for it.

What can I say? OMG Zombies! is an addictive game until you reach Prestige level 1. Play dominos with Zombies by watching them explode, shoot other zombies, scream (causes wide spread damage) and other crazy effects. You start off as an officer that appears to have gotten himself into a bit of a pickle. The way for him to survive is to down as many zombies as he can to process to the next areas in your journey.

Although you don't lose any health and you have no health for that matter makes the game too easy. You're basically on top of objects in the game, sniping zombies to try and cause a massive widespread train wreck. At first you only have 3 bullets, but upgrading let's you increase your clip size. The upgrade system is pretty fluid. Upgrade zombies, barrels or your own weapon.

Do I recommend this? Well, if you want to spend X amount of hours successfully getting the highest medal in all the levels, yes, I will recommend it. However, if you're looking for a game to play well over 30hrs, this game isn't that.

The downside I hated more than anything was levels 82-100 it kept spamming the comic like cinematic over and over again. I got the point that it was trying to tell a story, but as I progressed, it just looked like the same comic that was showing up until I got in the 90's. It showed different images, but overall it looked the same until level 100. If there was a way to turn it off, I would've done it in a heartbeat.

One last downside is the last achievement in the game. The achievement states you need to get Prestige level 20. 20 is a lot honestly. Even though it doesn't seem like it takes you forever to beat a round, doing it 20 more times will be literally redundant. The game isn't THAT addictive.

Another instance of a mediocre flash game making it's way to steam, OMG Zombies is a perfect example of Valve's incredibly lacking quality control.

The premise is standard click n' watch affair, where you click on one of a handful of zombie types and watch 'em wreak havoc on the rest, the point being to destroy all zombies with the fewest amount of bullets. The game is surprisingly slow and plodding, even given the genre, and it looks absolutely terrible. It's supposed to have your standard indie pixel graphics, but instead it just looks like it's been stretched way too far to look even remotely good.

The same premise has been done countless times, for free, and in better fashion, too. There is absolutely no reason to pay for something lesser than the free flash games that can be found on

I first played this game as a "mini" for the PSP/PS3. I drained the battery on my PSP many times playing this. I had it because of a PS+ membership. Once I let it lapse I realized that this was really the only "free" game that I missed. When I saw that it was for sale on steam I jumped right on it.

It's much better on Steam vs. PSN. More enemies. Better upgrading layout. And cleaner smoother graphics.

If you already have this game on a console or hand held and enjoy it. I highly suggest buying this version anyway. You won't be dissapointed.

In OMG Zombies you take the role of a survivor/shooter, perched on top of something higher than the Zombie horde below you on a 2D single screen, encompassing the various obstacles and challenges of each map. Armed with just a sniper rifle and 3 bullets (which you can upgrade to 6 as you earn cash by completing levels), you are tasked with taking out the entire screen's worth of undead. An impossible task if one bullet equaled one zombie death, but this is where OMGZ's strategy comes into play.

Each and every zombie in the game has a chain reaction ability which helps take out other zombies around it. Some explode, some fire off gunshots of their own, others run through the level screaming (taking out others at their destination), some even melt into acid; all of which helps clear the screen and earn you the higher ranking, providing you with more cash and allowing you to beef up your abilities.

Each level has a Bronze, Silver, Gold and Platinum medal to acquire, each earning you more cash for upgrades. Don't get discouraged if you can only pull off the lower medal awards at first, it'll become easier once you've spent some of that award money on upgrades. Better medals open up more and more of the 100 levels included and you can go back any time to any level and try for a higher score; some levels being clear-able in a single shot if timed right.

Thankfully the mouse is the most precise tool for the shooting, giving you an advantage over it's previous versions (on PSP/Vita). The game runs wonderfully in windowed mode and goes along at such a pace that you can continually go back to it between browsing and chatting if you prefer (which I liked during my play for this review).

What unfolds is a game that feels a little over-powering at first, as you clamor to get even a silver medal, then opens up and gives you the upper hand as you progress, only to keep challenging you with levels that make you wonder how even 6 bullets will help you be victorious. Sometimes timing is key and you can sit there with hand on mouse for what feels like forever, trying to line up the perfect chain reaction.

Then when you've completed all 100 levels on platinum, you have the choice to start all over again in a prestige mode, in which you lose all your upgrades and must start from level 1 again. Reminding yourself just how hard it was starting out. If you're brave enough and have some serious time to dedicate to it, the game has an achievement for prestige-ing 20 times over.

The game isn't a super action romp and you shouldn't get it thinking it is. It's a strategic game that employs a very well ramped difficulty curve which makes for an engaging and addicting experience. I've enjoyed my time with it and feel it's well worth the asking price.
