It started out as a mini-game inside Project Gotham Racing 2 for the original Xbox but Geometry Wars has grown since then to become a well known stand alone game franchise on its own. This week, the arcade shooter series gets a new installment, Geometry Wars 3: Dimensions, from UK-based Lucid Games. It’s being published by Activision as the first game under their revitalized Sierra brand, which will be dedicated to launching smaller, downloadable titles. Geometry Wars 3’s biggest feature is that it uses 3D grids for the first time, as players control their ship and combat a variety of enemies with different power ups in its unique retro art style. The game is out this week for the PC, Xbox One and Xbox 360 platforms, among others. We got a chance to ask some questions, via email, to Lucid Games co-founder Craig Howard about their work on Geometry Wars 3.
