Screamer 4x4 lets players loose on rough terrain in a range of modified off-road vehicles, ranging from the simple Land Rover to the massive RÁBA H18. Players compete in a series of time trial championships and trophies, earning new vehicles and upgrades as they go. There is a variety of play modes, including the option of a free drive (like Midtown Madness). Additionally, there is a range of multi-player games reminiscent of Carmageddon.
