I made a video game called Undead Fields using Linux and Blender. I exported the game for Linux and Windows but you can still use the original .blend file for your own purposes. You can download the game from here. I wanted to make a game that runs well, looks nice and is fun to play using my favorite operating system!
In the game, you are in an abandoned shack surrounded by the undead. There are also huge mega robot zombies that you have to fight. There are 3 hidden guns throughout the map that you can find. You can slow down time with the right mouse button. The Tab Key switches weapons by the way.
Please give me feedback about the game. Maybe ideas for performance, scenery, graphics, etc.
