"Forbidden Terror on Station Z!" was one of Emergent's 2008 GDC tech demos. Think "Zombie On Rails Shooter In Space". With a WiiMote.

This is a full gameplay demo on 4 platforms (Wii, PC, PS3, and Xbox 360) created in under two months with a small team of ~4 people and some contracted artwork and sound.

We started the project in-house as a product demo for our Nintendo Wii engine two months before GDC, decided to add PC a month later, then decided to add PS3 and Xbox 360 roughly ~3 weeks before the show (the initial porting for each of those platforms was about a day a piece).

So ... less than two months to get this tech demo running on four platforms, and catering to each.

Yeah, I'm really proud of the guys for that.

It is not meant to be a polished game, but to demonstrate how much functionality (including integration with other middleware) can be produced in a short time by a few developers.

The demo was built on Gamebryo 2.3, and video is from the PC version. The full source code (upgraded to Gamebryo 2.5) and assets will be available to licensees and evaluators in July 2008.
