I’ve just had a quick play through of a rather interesting game. It’s called Gravity Bone, and it’s a very short (two levels) game based on the Quake 2 engine (which isn’t required to play) and focusing on espionage. It uses a brilliantly cubist style that makes up for what the engine can’t handle, and at the same time makes it seem like one big advert from the 50s. It’s kind of how TF2 would look if Valve had gone the whole way. It’s a bit crazy, and I’ve never seen anyone get that… violent over a few pictures.
