Quake x Minecraft + Nine-Player Splitscreen = Gunscape | Grab It

"A rather succinct (albeit crude) way to describe Gunscape would be a love letter to the entire FPS genre. At its core Gunscape plays out like a classic arena-style shoot-em-up – such as Quake III Arena – including typical game modes such as Team Deathmatch, Free-For-All and CTF (Capture The Fish.) But Gunscape is so much more, with Blowfish Studios preferring to label its game a “FPS Construction Kit.” Indeed, Blowfish Studios is putting a massive focus on the community with creating, editing and sharing player developed maps integral to the experience." – Grab It
