About the Liberated Pixel Cup

Liberated Pixel Cup is a two-part competition: make a bunch of awesome free culture licensed artwork, and then program a bunch of free software games that use it.

Liberated Pixel Cup brings together some powerful allies: Creative Commons, Mozilla, OpenGameArt, the Free Software Foundation, and you.

The artwork

Phase one of the competition is to build a set of artwork that's dual licensed under CC BY-SA 3.0 and GPLv3 and stylistically consistent.  To that end, have created a style guide which incorporates these components.


As you can see, for this competition we're working on an overhead 16 bit rpg inspired style (technically: front-facing overhead orthographic view) with 32x32 tiles.  The selection of this style is intentional: we're trying to build something easy to collaborate upon on which a wide variety of games (overhead shooters, RPGs, adventure games, strategy games) can be built.

When the competition began on June 1st, artists were asked to make artwork that matches this existing style and upload to OpenGameArt.org under the forementioned licenses.  These entries are now archived here. Winners will be selected on judgements of quality, how well they match the style guide, etc.  Phase one runs from June 1st thru June 30th. For more information, check out the rules.

The games

Phase two of this competition will be building GPLv3 or later games that incorporate artwork from the artwork building phase of the project.  People can work in teams or individually.  Participants will be judged based on fun factor, innovativeness, and of course how well they incorporate assets built for the contest. Phase two runs from July 1st thru July 31st.

Please note that for a game to qualify as a contest entry, it must compile and run on 100% free (as in freedom) software from the ground up.


Liberated Pixel Cup will be awesome, but it can't happen without the help of people like you!

We're paying artists for comissions on the artwork for the initial style guide, and we'd like to give away prizes for those who win the competition.  You can help make this project all the more awesome with your donation!

This competition also needs people like you to enter and do awesome things with it.  Interested in taking part?  Read up more here and join us at #liberatedpixelcup on irc.freenode.net (click here to chat from your browser)! The admins and judges can be reached for questions on the official forum as well.
