Mediecross Mini-Game

Anonymous Aug 26, 2010 at 14:00


Mediécross is a mini-game that was made for a one month contest held by the website The topic of this contest was to create a game inspired by a so-called “fake game cartridge” of the Japanese “Famicase” collection.

Our game takes place in a world made of clay, similar to what is shown on the cartridge below:

The graphic style is all in 3D, trying to mimic the clay aspect, the lighting, and the color scheme of the original cartridge, as much as possible.

The Game

The game design itself is loosely based on the original arcade game ‘Metrocross’ by Namco. The player must run in a corridor, avoid the obstacles (barrels, slowering tiles…), jump on the bumpers, get some items for extra-time, reach the end of the corridor.

The final game runs in a game engine, named ‘GameStart’, that I’ve been using for years, and that is now entering in its commercial stage.

Production notes

The gameplay prototype was created quickly, along with the creation of the graphic assets, using GameStart. The developer of the engine, Emmanuel, entered in the loop only during the last week. He rewrote practically all my messy script (I’m a 3D artist, mainly), and made the gameplay stable & reliable enough to allow a fast level design.

Because the engine renderer uses the Deferred Shading technique, as an artist I really felt empowered. Colored lights, dynamic shadows, abstracted shaders allowed me to emphasize the story telling without having to fight with the rendering pipeline.

Along with the 3D modeling & developpement of Mediécross, we had an animator involved, Ryan Hagen. It is most notable that Ryan works in the US, and Emmanuel & myself are located in France. The versioning system SVN proved itself of great help so exchange the data safely, and the native format of GameStart is adapted to SVN. To exchange the 3D data (models, animations …), we worked with the FBX format, allowing us to build a production-proof pipeline between 3DSMax, Maya and GameStart.

Considering a project done on our spare time, the game shows nice visuals, a rather decent gameplay, and was a positive validation of the workflow built on GameStart.

Emmanuel wrote a comprehensive ‘post mortem’ of this small project, and released the whole sources of the game. Find all this stuff on the GameStart website mentionned below.

Hey Guys!
The engine that helped us to make this game is now in Public Beta.
Feel free to download the Windows Binary and test it !
