Between PC, iOS, and Android, there are a lot of free zombie games that are definitely worth your time. With so many options, let's take a look at the best zombie games you can play for free right now, and rank them while we're at it. If you have a computer or smartphone, you'll be able to play any of the free games with zombies on the list below.
There are several good free zombie shooting games, including popular mobile games like Dead Trigger 2 and Zombie Frontier 3: Sniper FPS. If you want zombies without the violence, check out Plants vs. Zombies, a free tower defense zombie game where you use plants to ward off the undead in your own backyard. Once you pick it up, you won't want to put it down.
For the PC gamers, titles like No More Room in Hell and Codename CURE are pretty amazing zombie games considering they are 100% free. They are very much on the realistic side, but to tone it down you can play something like Zombidle : REMONSTERED, which is a significantly more lighthearted take on the walking dead.
If you want zombie games for free, this ranked recommendation list will have you mowing down walkers in no time.
In terms of pure gameplay and overall enjoyment level, it doesn't get much better for a free zombie game than Plants vs. Zombies. Defend your backyard from waves of goofy zombies by planting special flowers, plants, and even walnuts that will help you defeat the undead. The zombies are hilarious and have unique attributes, such as cones on their heads to make them more resilient to your seed bullets. You won't be able to put this down once you start, so don't be mad if you end up staying up all night playing. Be warned that Plants vs. Zombies 2 is an awful freemium game that tries to nickel and dime you at every turn, so you're better off playing the original.
