Contagion isn't your average Zombie Shooter but instead takes a more realistic and different approach to the popular genre with unique characters, environments, weapons, items, and a built in system that makes every round completely unpredictable with resources, objectives, and paths ever changing.

Originally I gave this game a positive review because of it's potential and it's survival horror elements/gameplay. My friends and I had a lot of fun playing this game even with the limited number of maps/overall content.

However, I'm changing my review due to the communication between the developer and its community. The developer for this game cannot take constructive criticism. How these guys deal with this is awful. I'm not upset about the wait for the new content. I understand it's free which is great. I am upset that they deal with their customers so poorly.

Pass on this game.

A clunky zombie survival horror game with extremely delayed patches and DLC that had been promised, with numerous developers leaving the company and with a manchild developer falsely banning people from the games steam forums for expressing discontent with the games current state and the development cycle. As for the game, it is dated visually, has extremely bad movement controls, has really bad gunplay, and allows for easily exploitable maps in which most people just camp in one spot. Also, the player counts at peak times are abysmally low (lower than 50 sometimes) Avoid like the plague.

I bought this game over a year ago because they promised a multiplatform game win/mac/linux (and I use Linux). So yeah, after all this time waiting for the Linux release, they still didn't released the game. What I can say is I'm tired of liars. ONE FREAKING YEAR!!! I think is more than enough time to do a ♥♥♥♥ing port of any source-engine based game. So yeah, I'm here just to say: YOU, contagion developers, You suck!

EDIT: There are some stupid people that keep talking ♥♥♥♥ about what they don't know. The problem is they sold the game with a "Linux" icon ON THE STORE PAGE! Is that so difficult to understand? I don't give a ♥♥♥♥ if a company don't want to make a game for Linux, BUT if they put a Linux icon and GET MY MONEY, I demand what I paid for! Nothing less, nothing more! Just FYI, there was no "refund policy" at the time. Thanks to Valve, this is not gonna happen anymore!

THAT SAID, Troll comments about my personal OS choice will be deleted. Period.

What I liked:
  • You become a zombie instead of watching when you die
  • Is a hard game on some maps ( you can't always shoot your way out )
  • Escape mode is fun when I can find a game
What You Need to Know:
  • Has the smudge on camera effect
  • Graphics and effects are good
  • No one is playing this game
  • No More Room in Hell has 10 times the average players at any given time
  • The only mode I like has 4 maps (1 which is just boring)
  • Play No More Room in Hell instead

My Score:

Paid: $5
Completed in: No one plays
