If you want to play all by yourself or with some friends on a private server, you just have to follow these 4 steps.

1. Go to your Steam Library and find "Immune". Right click on the name and click on "Properties" in the context menu.



2. In the "Properties" dialog you have to click on "Local Files" and then on "Browse Local Files".



3. An explorer window opened. Make sure the Immune game is closed before you double click the "start_server.bat". A small command window pops up for a split second and disappears again. Now the local server is up and running. You can see the "Immune.exe" in the Taskmanager. The Taskmanager can be opened with CTRL + SHIFT + ESC.



4. Open the game Immune and enter the IP "127.0.0.1" into the custom IP field and press the connect button on the right.



You should now connect to your very own server, running on your machine. If you are finished playing you just kill "Immune.exe" in your Taskmanager (open with CTRL + SHIFT + ESC) by clicking on it and pressing DELETE.

Have fun! :)
