OMG Zombies! is a puzzle game where the idea is to create chains of exploding zombies by firing your weapon at them. Each zombie has a different ability that has a different effect on the chain. Players need to work out the positioning of the zombies, the type of zombies in the level, the layout of the level and the upgrades they may have earned to create the largest chain possible and hopefully rid each level of 100% of zombies.
The concept whilst solid does leave a little to luck as well as judgement. The biggest frustration is that a level will have a slightly different layout of where zombies are, so there is no way to work out the best possible combination of shots across various attempts. This means that whilst aiming in the same area may clear 55% of zombies in one go, the next time it may clear 91% it adds an element of randomness that does away with the puzzle element somewhat. That said, it is a minor frustration and replaying levels doesn’t tend to bother you, as you’ll soon find you have lost a lot of time whilst trying to clear each level.
Depending on how well you do on each level, you are awarded with a bronze, silver or gold medal and a cash prize. Medals earned open up new levels and money can be used to buy upgrades. The upgrades really work well in OMG Zombies too, as not only can you upgrade your weapon, to give effects such as more power, but you can also upgrade barrels so the explosions are greater and affect more zombies. You can also upgrade the various zombie types so that their abilities have better effects.
There are loads of levels each with slightly different themes and layouts, so despite the simplicity of the concept there are a good few hours of gameplay here, especially if you plan on getting 100% on each level. Doing so isn’t easy either, as there will be times when you’ll hit a massive chain, have two bullets left, but have three zombies to kill who are not even close to each other.
Overall OMG Zombies is a fun little time waster. Despite the randomness of layouts on levels, when you hit a mammoth chain the feeling is great. The fresh undead types and overhauled visuals will offer something new for seasoned slayers, while the sheer satisfaction of the core gameplay loop will delight newcomers.
