Made by modder JulioNIB, the work drops the ED-209 robot from Robocop directly into GTAIV. You can control the bot directly, let it play bodyguard for your character or just let it go on a complete rampage. Let's hope it negotiates stairs better than the film version, though.
Now, the game just needs the 6000 SUX and some Ford Taurus police cars to complete the look of the film. JulioNIB wants to eventually add the ED-209 into Grand Theft Auto V, as well. Scroll down to see two videos of the robot in action.
