My favorite zombie mod for any game. Even though the game is very slowly dying it still holds a very special place in the modding community.

PROS -
Fun to play alone and with friends
Requires a lot of team work to win a round
No specific roles, anyone can hop in and have fun
The cading in the game is very fun to play with

CONS -
Starting as a zombie can be very slow
Prop blocking and impossible cades can occur and makes it frustrating

Overall the game is very fun with only a few bitter moments to be found and this is only a mod.

Final PERSONAL Verdict - 8/10

Played this game to bits several years ago. Great soundtrack. A slow, creepy and immersive zombie survival game where you either work together as survivors to finish the objectives and escape, or team up with your fellow zombies to overwhelm the humans. Teamwork is a must, no matter which team you're on!

I really like this game a lot! It's one of the games that I play most frequently. But now that I do not own a Windows computer anymore, I have a Macbook now but the game is not playable unless it's on Windows. I really wish they can make the game available on Mac.

let me start off by saying I swear I don't have severe down syndrome, I just write steam reviews. Zombie Panic! Source is an indepth game about deriving Einstein's Equations. In this game you will learn to master the art of water bottle making, and more. Not to mention the great atmosphere of flying a kite, and drinking coke zero. How ever some cons are
  • Sour, yet sweet.
  • not enough dank memes
  • ????

overall e^i/10

It's ok.

Survivor side is fun as hell, you scavenge weapons and ammo, do objectives and escape the zombies.

Zombie side is boring, tedious and difficult. It just bores me whenever I am a zombie (I don't mind being the first so much as there's plenty of targets but later on its slow and boring and when you find someone you die pretty much instantly).

I would recommend it to zombie game fans but not really to others since the download is massive and it gets tedious after a bit in my opinion.

6/10

A free mod, if you have a Source Engine running game, like Hl2, CSS etc.
Thanks to Half-life 1, Zombie Panic was spawned and thus after Hl2, a source engine running ZP was made as you see here.

Mainly really only a multiplayer game, players start out having to survive or escape the map, following objectives.
Soon after round start a random player will be picked to become a "special" zombie, one that has a larger chance of infecting players. When a player dies, they become a zombie themselves and must help kill out the rest of the surviving players.

Around the map you can find different sorts of weapons, ranging from melee to long/close range based weapons. The game also uses a ammo system, which you can decide what kind of ammo type and how much you want to drop. You see, the more you carry, the more burden you get, and become slower. You become a easy target for a swarm of zombies.
Items also include health packs, pills, body armor and wooden planks you can use to board against windows or doors to keep out zombies for a small amount of time.

The mod has a thriving community with a decent amount of servers, and there's loads of custom maps incase you become bored of the usual classic maps.

Overall I would highly recommend this mod if you enjoy zombie games.

It's a fun zombie game that requires a lot of teamwork and strategies.

+ Cool mechanics;

+ Decent graphics;

+ Runs in every PC (Seriously);

- Most of the time, people just want to ♥♥♥♥ around and not play the game seriously. That means: destroying barricades made by other survivors, not sharing ammo, or caring about the rest of the group, and the list goes on;

- The amount of custom maps is absurd, but sometimes you just want to play in the official ones.

A zombie survival-themed cooperative game in which you have to face hordes of zombies. The concept may seem like a cliche within the genre but the gamemode's entertaining nature easily makes it a great must-have as a Half-Life 2 Mod. Starting as a human might be hard for newcomers but the learning curve isn't all too steep as the game requires both teamwork and tactics to accomplish the objectives in the game.

I've noticed that a noticeable percentage of reviews bash the gameplay while playing as a zombie for being too slow and tedious. Having played gamemodes like L4D2 and Zombie Survival on Gmod, I agree to a certain extent while at the same time, I find the overall experience to be really satisfying.

If you have friends to play Zombie Panic: Source with, don't miss the chance.
