A violent FPS based on the famous comic book series from 2000 AD.
The production value is somewhat poor. The graphics look very dated, the animations are jerky, the AI is stupid, the vampire and undead enemies are poorly coded and animated, the level design sometimes feels very obtuse, and there's a plethora of weird bugs.
However, if you're a fan of the comic book, there's certainly fun to be had here. Rebellion nailed perfectly Judge Dredd's unique sense of humour and the rendition of Mega-City One is spot on. It's violent, gore, stupid, hilarious at times, and pure mindless fun.
The headshots are awesome (instant bloody decapitation!). You can immolate people. Kill by ricochet. Fire homing bullets. And even reliably disarm perps by shooting their weapons off their hands, allowing you to arrest them, instead of killing them. You can also kill your allies and civilians. It's funny that you can abuse of your authority to arrest innocent civilians, while listening to their complaints make it all the more hilarious.
Aside from the solo/coop campaign, there's a survival mode and many LAN multiplayer modes (you can replace humans with bots too). The multiplayer games, being fast and violent, can be very fun to play with a group of friends.
