While the game itself, like it's predecessor Pixel Puzzles Japan, is quite enjoyable, it still has the same key issue: you cannot save the puzzles, a thing you can do with real life puzzles even. It is also somewhat easier than the Japan version due to using drawings instead of photographs.

There's a tacked on "survival mode" with a shooting game going on in the lower part of the screen, as a kind of hard mode. A nice idea, but mediocre in execution.

Images vary from good with funny motifs to half amateurish, which is a shame. There's fifteen puzzles in total, if they had gone with their better illustrator for all of them it would have uplifted the whole game.

What finally prompted me to go for a negative rating (instead of saying it's mediocre and still giving it a thumbs up) has to be that one last achievement though. Completionists, stay away from this unless you are prepared to suffer!
There's a menu mini game, which has several achievements tied to it. Some of them are for killing a certain amount of menu zombies. The first ones stack, the last one apparently doesn't. So essentially I'd have to start all over again for that last one, because I was tricked into believing I could give my eyes a rest after over an hour of the most boring(!) achievement hunt period.
Doing hard achievements is one thing (and welcome), but this was simply a sadistic and dirty move from the devs on behalf of hunters. So, to return that "favor": here you go, Decaying Logic, while being overall not very much disappointed by the game, I choose to make that one, tiny last bit under my review a big thumbs down. Feels good, feels right, doesn't it?

Best game of the series! I first played Pixel Puzzles: Japan and fell in love so I bought this one. This game is a strictly BETTER. The developers have added a save puzzle feature (yes finally!), overlay feature (to help you solve a puzzle IF you need it) a mini game for the main menu (with steam achievements) and of course a completly new twist -> try to complete a puzzle while zombies run at your characater and you have to defend yourself. Now this game has a lot of negative reviews - why? - because it is not obvious to all players that you HAVE THE OPTION TO TURN OFF THE ZOMBIE INVASION and solve your puzzle in peace :) I highly recommend it!

Pixel Puzzles Undeadz is one of the best in the series where you try and stay alive by killing Zombies whilst trying to complete Jigsaw Puzzles. It's really challenging, fun and the puzzles are graphically stunning. However, I can't recommend it and here is why.


♦ Great Graphics (The Graphic design for each Puzzle is stunning)
♦ Challenging yet fun Gameplay (Having to juggle between completing a Jigsaw Puzzle, Killing Zombies and Staying alive is really nice)
♦ Nice number of weapon upgrades or completing x amount of the Puzzle (This is a nice reward based concept)
♦ Great number of Puzzles (Not too many and not too few, about the right number)
♦ Menu Zombie Kill Minigame is an awesome touch to the main menu (Though it's really hard and doesn't scale properly, by the time you kill 15 Zombies, it's really hard to stay alive no matter what you do)
♦ Decent Number of relatively easy achievements (This is great as you don't really have to do anything special to get the achievements, the only problem is the main menu minigame achievements)
♦ Graphically Stunning Steam Trading Cards (This is always a good addition to any Steam Game)
♦ Decent Price (For the effort that goes into the graphic design of the Puzzles it is worth the price and the Zombie addition gives nice Gameplay)


♦ No Cloud Save (This is terrible, if a game is on Steam and doesn't make use of this feature... then it shouldn't be on Steam for obvious reasons)
♦ The Kill 5000 Menu Zombies Achievement is almost impossible (You have to kill all 5000 in one go, which sucks as I found killing 15 to be inbalanced enough)

Overall, for a Jigsaw Puzzle Zombie Killing game, it mixes the two modes together nicely and has way more Pros then Cons. However, for the sole purpose of not having Cloud Storage, I recommend you do not buy this. This is because nowhere does it tell you it doesn't sync to cloud storage and for me, I beat 9 Puzzles and Re-installed Steam for whatever reason and none of my Saves for this game were there. Thus, for a game that takes a lot of time and effort to beat a Puzzle I don't really want to have to redo all 9 Puzzles that I had already completed. Therefore, even though it is a decent game, to save you the hassel of having to start over like I did, I wouldn't recommend it as it doesn't use Cloud Storage.

I agree with the review of the current top rated comment. If anything, he understated the game's problems. If you want 100% achievements, not only do you have to play the world's worst minigame for a very long time, you have to do it flawlessly. If you die once, you have to start again. It's quite easy to die. They should have stuck with jigsaws.

To be honest, I'm not entirely sure if I remember how I came to own this game. I'm going to assume it was through a bundle. Nonetheless, I'm glad I discovered it.

This is much like the other themed puzzle games here on steam; this one obviously depicting zombies in some state of affair or at times the survivors of an assumed but not often eluded to zombie apocalypse. But this one has a twist that I think sets it apart.

A TIMER *gasps surround the room in a cacophonous roar that affronts your ears and causes them twitch with fright searching for its source.

(Note: This can be turned off should you just want a normal puzzle solving experience.) The timer counts down to a zombie horde that will attack your base. In between waves, stray zombies will show up to keep you on your toes. What makes this more than just a timer is that must actually shoot the zombies yourself. There is only one lane so its not super demanding but you must WASD around and firing a rifle and throwing grenades allowing yourself enough time to solve the puzzle.

This makes the puzzle more engaging and frantic as in true survival games resources are scarce. You'll run out of bullets and be forced to solve more of the puzzle in order to get more money to buy more ammo at the shop. There are also mines among other explosives at your disposal that effectively rise in price as the more effective they are at exacting death the more expensive they will be.

It may not be the most original idea but it is an interesting and novel idea to say the least.
