Gunscape Unveiled, Demo Released

The demo allows players to build their own FPS worlds with a limited set of game elements and then to publish their world for everyone to play
Created by Blowfish Studios for Windows, Linux and Mac, Gunscape aims to be the start of a new evolution of FPS games by combining accessible level building and sharing functionality with core FPS single player and multiplayer gameplay. It does this by providing easy-to-use tools based on a block-placement interface everybody's already familiar with to create single-player campaigns, co-op maps and multiplayer arenas and the functionality to share your creations with your friends and others.
You can support the game through these Kickstarter and Steam Greenlight campaigns - the latest pre-alpha demo is locally mirrored.
