Warsow is a multiplayer first-person shooter computer game. It's codebase is free and open source software, distributed under the terms of the GPL; it is built upon Qfusion, an advanced modification of the Quake II engine. The artwork and other media are licensed under the proprietary Warsow Content License, which allows the contributors of this media to use the work in a "personal portfolio" but not in any other game. Warsow is loosely based on the E-novel Chasseur de bots by Fabrice Demurger. The novel is the basis of the game's cyberpunk visual style, which is achieved by combining cel-shaded cartoon-like graphics with dark, flashy and dirty textures. Since visual clarity is important in maintaining competitive gameplay, Warsow tries to keep effects minimalistic, clear and visible. Source: The Developer Website.
