It's easy to forget that Counter-Strike Online is a thing, given that Valve don't typically license out their games to other developers and publishers, but the free-to-play spin-off has been going for about six years now, under South Korean developers and publishers Nexon. Following the release of Counter-Strike Online 2 a couple of years ago, Nexon has announced another entry in the series and, naturally, it's themed around zombies. Free-to-play multiplayer FPS Counter-Strike Nexon: Zombies will be heading to Steam this Summer/Autumn.

It seems that Zombies will mix more traditional CS game modes such as Hostage Rescue and Bomb Diffusion with new ones that will shove zombies in as well. These modes haven't been detailed yet, but Counter-Strike Online's Left 4 Dead-like Zombie Darkness mode might hold a few clues.

Valve's Doug Lombardi can hardly contain his excitement:

“Today we are announcing the latest creation from Nexon in the Counter-Strike world, one that builds upon years of success in developing CS Online for Asia. This title showcases that work in new, zombie, and classic form.”

Here's hoping Nexon goes the whole hog and chucks in a Portal gun and TF2 characters for their next Counter-Strike game. Zombies is out soonish, and unlike Counter-Strike Online, you'll be able to find this one on Steam.
