Zombie Driver HD has been around for a long time – and it’s a super-fun, violent driving game. Now, after years of releases on the Xbox 360, PlayStation 3, and even the OUYA, it’s now free on PC via Steam. The publisher of the game, Exor has a big sale going on. This is a way to get people to try out at least something of theirs, and still be impressed enough to pay for something. This game came out in the height of zombie-mania and offers a lot of fun if all you want is an overhead-viewpoint version of Carmageddon. If you want to just turn your brain off for a bit and destroy a bunch of zombies, it’s a great impulse buy anyway and for free, you can’t go wrong.
