As previously announced, ZomB Battlegrounds - Supporter Edition is now available as a free download due to the online services for the game shutting down today. All players of the game now have access to the Supporter Edition exclusive features such as the Tutorial Video and Steam Achievements, however you will now be unable to access features that rely on external servers, such as the Server Browser and playing online. It is still possible to play the game offline in single player against bots, or in multiplayer over a LAN connection. There have been no changes to the game itself other than the online services shutting down.
Starting today, I have also released the very first Steam build of the game (Version 3.0.0) under the "OldVersion" beta branch on Steam. This version of the game should have an easier time running on lower end hardware, so if your computer is having trouble running the latest version of the game, I'd recommend giving that version a try. Just know that version 3.0.0 is almost 6 years old at this point, so as a result it is missing a lot of the content and fixes present in the newest version of the game, and you will not be able to earn any achievements.
I would like to thank all of you for supporting the game, I never expected it to last as long as it did, and I definitely never expected to keep updating it for as long as I did, and it only happened thanks to support from you!
ZomB: Battlegrounds is now free!
