4x4 Evolution (also known as 4x4EVO, codenamed Metal Crush 3) is a video game developed by Terminal Reality for the Windows, Macintosh, PlayStation 2 and Dreamcast platforms. It is the first console game to have cross-platform online play where Dreamcast, Macintosh and PC versions of the game appear online at the same time. The game can use maps created by users to download onto a hard drive, and surprisingly a Dreamcast VMU. All games are similar in quality and gameplay although the online systems feature a mode to customize the players' own truck and use it online. This game is still able to play online with all but the Sony Playstation 2 systems. [source:wikipedia]
