The game is based on 2000 AD comics, more like the 1995 Sylvester Stallone movie. In this game you are the law and no clone brother or the evil Jürgen Prochnov. :) The graphics is so comic style, dark and dirty. And Dredd... well, he is a real though guy, forget Stallone! The game contains story mode with 11 level + the tutorial, Arcade mode with a few intese survival or slaughter style objective. And of course its has multiplayer Deathmatch, etc and co-op. Maybe this doesn't work, since Sierra not support the game.
Maybe not the best FPS ever, but who knows Dredd anyway or just like sci-fi aciton games will sure love it. The replayability factor is very good even if the missions are short, 'cause is not to easy complete all missions with Judge Dredd award.
