The fight for survival is on! OverDose is a class, team & objective based multiplayer game set on a post-apocalyptic Earth. With gameplay in the tradition of classic games such as Return to Castle Wolfenstein and Enemy Territory, melded with up to date gameplay mechanics and movement, OverDose is a unique blend of online action, team play and of course, lots of gore. Using id tech 2 as a base, OverDose features updated engine features like full real time lighting and shadow mapping, physically based rendering, particle and physics simulations and more. Plus, in classic id Software tradition, our engine and game are fully moddable and scriptable, meaning even amateur mod makers can bring their own creations to life with ease. This isn't war... It's an all out apocalypse!
In the old days skies in levels were made out of simple environment maps. These days, we can actually render a camera inside a volume and use that as a sky portal, to make levels look like they go on for miles. Inside the volume we can render effects, aniamtion, models, anything we want really. This sky portal is supposed to be used for high rise building battles. The idea is that you map close buildings, and then let the sky portal take care of the effect in the distance, thus making the level look larger than it actually is. A nice trick.
