Contagion Windows game

It has been awhile since we posted something here, which was back in... oh boy, 2015. Let's get up to speed on what we have been up to, shall we?

Back in November 2019, I (Johan "JonnyBoy0719" Ehrendahl) was hired as the new lead programmer for Contagion. In short, I was hired to fix the game because it was in a terrible state. Game was crashing left and right, Escape gamemode softlocked if the survivors failed the round, Extraction had problems with the AI survivors and Flatline was... Well, let's just say it was not in great shape. After rewriting Flatline gamemode from the ground up (everything was thrown out), it was finally out from Beta after 7 years.

After a single month, the major update was finally released in late December of 2019. Several more major updates was released from 2020 to 2021, bringing more content such as new zombies types, weapons and maps. The major updates slowed down in 2022, not because of lacking in productivity, but because we are working on something big. The recent update that was released back in 8th of April 2022, we released the first campaign ever created for Contagion called "Last Stop", which is the first chapter that comes with 3 new maps and a new character!

Contagion :: Preview of The Changes

Mike R. Gonzales "The Engineer", is a new character for Contagion. Voiced by our very own community manager, LordCommanderGuts. He is a new character that works at a fictional company in Last Stop that you will pass trough on the 3rd map on Chapter 1.

The Changelog

This combines changes from 29th of December 2019 to 8th of April 2022. But it does not contain everything, only some important bits. Basically a quick TLDR.
