This time through we introduce you to new characters that you can control, numerous weapons including a large list of melee weapons, and the Carrier zombie which can turn friend into foe. We started it all and are happily continuing the fight!

Good Half-Life 2 mod but was sadly abandoned due to the (not-so-great) developer's decision to only focus on his new game Contagion that features reworked classic maps from this game. However, the game is dead with only a few servers left which I could probably name right now. Most of the players aren't on Steam and don't speak English no matter what the server rules say. Although it's free, I can't recommend it simply due to the fact that the developer abandoned it and the playerbase is lacking and the little that is left isn't great at all.

This mod is a gem. Hell i wasnt even a fan of the whole zombie genre when i tried this game out of curiosity five years ago but it quickly won me over thanks to its gameplay and atmosphere. Its immersive, challenging (teamwork is a MUST) and above all, fun.

An interesting aspect of the game is that you actually can play as a zombie after you died. No bot slaughterfest à la Left 4 Dead here. Its very enjoyable to fight a zombie horde composed of other players trying to overwhelm you so you can join their ranks. Zombos can also infect you which really adds to the tension since it creates a climate of suspicion among the survivors.

Most of the official maps are well designed and interesting. The character models are well made too and all have their own "personality" and dialogue lines which is pretty cool.

Last but not least, there is a really nice variety of weapons, including several melees. There is also a barricade system that can help you to hold off the undead. I should also mention the weapon and ammo management system. Guns and ammo slow you down so hoarding ammo is not an option. The weapon/ammo weight plus a fatigue bar adds to the realism and makes being a team player an absolute necessity.

If you are looking for a fun, teamwork oriented zombie survival game, give it a try. Chances are you wont be disappointed. And remember, its FREE. :)

If You're Reading This Now, Install This Game And Play It. You Won't Regret It.

Ah, ZPS. Words cannot describe my deep love for this true gem of a game. I started playing ZPS around early 2008 on my old account, and every second of it was a blast. The atmosphere, the frantic teamwork, the soundtrack and the gunplay was once the pinnacle of 2007-era Source multiplayer. The rush of joy at your first survivor/zombie kill. The great relief of surviving a horde, only to be faced with the overwhelming pressure of being the last survivor on your team. All of this combined and much, much more gave ZPS it's once shining luster.

Skip forward almost 8 years later, and ZPS is more-or-less dead. The average number of dedicated players is abysmal, developer support is non-existant, and the only thing keeping ZPS barely alive is the community. It truly is a tragedy, how much has changed in such a short time, and all for the worst.

Contagion tried (and failed) to preserve the original beauty of ZPS. But with almost all of the ZPS team gone to places unkown, the true spirit of ZPS is in risk of being lost forever.

Though there have been petitions on popular websites such as change.org, all we have recieved so far are empty promises from a struggling dev team. Unless something changes, and fast, the crumbling foundation of the ZPS community could very well collapse, and more quickly than we think.

Therefore I pay my final ode to ZPS. Chances are, come back in a few years time, and ZPS will practically be unheard of. Hell, there may not even be a store page left to view any more. Or reviews such as this.

All we, what remains of the ZPS community can do, is continue to play ZPS in the vain hope that our meager efforts will keep ZPS alive. All we can do is spread the word to new players. All we can do is build groups and servers. All we can do is demand updates and a little bit of TLC for ZPS, even though it's bound to never happen in our lifetimes.

Therefore I plead you one more time; If you are new to the concept of ZPS and do not play it, click that green install button right now and launch it up. You will not regret it, trust me.


That is all I have to say. Thank you for your time.

Thanks to ZPS for all fun and hardcore gameplay. This mod is absolutely the best. Also this is the most interesting and intense zombie game I have ever played. Of course I recommend this game to play.
