Contagion Update..!

Wait...Contagion Update?!

Well, it might have taken the better part of forever, but we've got another update rolling out.

First off; a big, huge props and thank you to CCL sama for providing fixes to navmeshes for bunches of maps. Lots of zombie nav weirdness fixes and all around improved navigation should be expected.

We also have rebuilt the workshop tool from the ground up, making it a lot more usable, pretty, and bug-free.

There is also some very exciting new stuff coming up on the horizon soon, but we wanted to get something out since it had been so very long since Contagion got any proper love. While I know this isnt the update many of you were hoping for, we are still determined to fix all the issues left in the game and add the features that need to be added. Things are not moving at the speed any of us would like, but they are still moving.

Thank you to you all for being patient (and thank you as well to those of you whose patience has worn down. We're gonna work on earning it back)

I was following this game when it was annouced for the first time back in the day.
I was hyped about it and i couldnt wait more for it, when it came out on kickstarter i was amused, but sadly i couldnt afford for backing monochrome back then.

When it was released on steam i had the moneys so i bought it and i noticed it changed a lot compared to the alpha videos on the official youtube channel.

So heres my conclusion, these are my pros and cons about this game:

+ Its a spiritual sucesor to ZPS, so you can feel it has a little bit of it, it even has a Panic gamemode which tries to be faithful to the original mod
+ Hunted mode is the gamemode that i spent a lot of time playing it back then
+ I like games that needs cooperation, and the matches i have been back then i encountered with people that was very communicative with the players and started helping each other.

- Now theres no activity on the servers, looks like the game is already dead.
- Flatline mode needs some fixes, like other stuff in the game.
- I have experienced some bad optimizations on the framerate on other pc's/laptops

Well, if you liked ZPS you definetly need this game, but i suggest you to organize a match with some friends because its rarely to find a server full of people to play with.

A once promising game, offering an intriguing addition to the over-saturated "zombie survival" genre.

Despite its successful initial execution, the development of the game has now been suspended (unofficially or not) due to the developers transferring their priorities to a different project. (such a shame really)

Recommend it only for people who believe they would truly appreciate it.

If someone wants an actively developed and constantly improved game, I recommend you choose a different title.

I bought this game thinking it would be a good old zombie survival/shooter, and it sure exceeded my expectations to be honest! Contagion has various game modes, all of which are playable solo (albeit slowly), but most of these modes are designed for co-op or online lobbies. The objective based modes are great, especially Extraction. I personally enjoyed the Purge styled PvP last-man-standing mode, it certainly tests your skills.


- Realistic zombies: Headshot is insta-kill (reasonably easy to do), or they take a lot of body damage
- Challenging gameplay
- Heaps of game modes
- Relatively active community


- Solo progression can be slow (grab some friends)
- Stamina function is reasonably short for the length of some objectives
- When respawning as zombies, you most often respawn way away from the action

Overall I recommend this game, for its excellent gameplay and basically doing what it advertises. It has relatively low requirements, so it is pretty easy to run on most devices, as well as being cheap.

You are a survivor armed with a assortment of various weaponry and a next-gen smartphone with unlimited battery against an horde of infected zombies.But the real danger comes not from the horde,no it comes from the very teammates you have to survive with....

In all seriousness this game is a nice take on using l4d's system with more of a walking dead bunch of zombies that die from headshots.

Gameplay:8/10-Quite enjoyable with strong amounts of co-op play.
Visuals:7/10-Dated but not a real eyesore.
Sound:8/10-The zombie horde causes a earbleed :D
Servers:?/10-I am unsure of the server status at the moment(will edit)

Overall:8/10-The game may lack single-player or a general plot unlike l4d but it is a enjoyable experience that I would recommend

Barely any levels for escape, cant connect with friends -at all- and pretty sure this game is either dead or getting there.

So happy game is working again!! This is by far the best/most realistic zombie game i have played. Its one of the only ones out there where you actually have to hit them in the head to kill them, and there is also a chance with every hit you can contract the virus, eventually turning into a zombie yourself (super fun when playing online from both sides). The zeds in this game are the classic romero slow lurching type but very limited resources coupled with the headshot thing mean things get intense fast,and when you do complete a map you get a real sense of "I made it" that few survival games give.

Absolutely immersive experience when playing co-op with some friends or PvP Hunted mode and trying to outlive the rest. Hoping for some more maps in future, but still a lot of fun to re-play often.

Its a great game that demonstrates the capabilites of online gaming and allows the player(s) to be as helpfull or unhelpful as possible. This is as real as social complexities get. I personally enjoy the escape mode, much like "Aliens Colonial Marines" in the sence of mission parameters not AI algorithums, and graphics. This mode has helped me demonstrate "game theory" as an evolutionary uniqueness between the human species. How Altruistic are we as a species? Games such as this one which places the character in a map trapped full of AI driven Zombies that resemble those from the original George A. Romerio movies can teach you about how you and others can work best together out of a similar predictment.
