Open Source Zombies!

Zombies! is a team-oriented multiplayer game built on the Nonoba multiplayer platform. I’ve decided to open source it to give other developers a source for inspiration or to develop another game on the same code-base.

What it’s got

Zombies! has so far over 500k gameplays, 20 levels, boss-fights, multiple weapons and upgrades, 4 different enemies, and deathmatch. It’s stable and it’s pretty simple for a game of its size with almost no code on the Flash timeline, so it won’t be impossible for other developers to quickly get an overview.


What I want you to do

Download the source and take a look. You might learn something šŸ˜‰ You have a free license to do anything you want with the codefiles that are not from Nonoba or otherwise contains a license notice.

If you want to make your own sequel to Zombies! or a differently themed games you must create or find your own graphics and sounds. How you decide to tweak the game beyond that is completely up to you. As long as you tell everyone about it if you do something fun with it šŸ™‚

What could be cool

The game was programmed in about 60 hours, so a lot of corners had to be cut. I would love for someone to take the game and make some cool additions. Some examples could be:

  • Barriers / obstacles for the players to hide behind
  • A completely new theme: Make it about humans and orcs or something else
  • Make it possible for players to move around a bigger screen so more people can play at once
  • More monsters, more weapons, more levels, more upgrades


All code specific to Zombies! is hereby licensed under the mWTFPL, which is based on the WTFPL. Look it up if you don’t know it šŸ˜‰


Get Zombies! here

You need Visual Studio 2008 to compile the backend. Download it for free here.
