4x4 Evolution (also known as 4x4 EVO, codenamed Metal Crush 3) is a video game developed by Terminal Reality for the Windows, Macintosh, PlayStation 2 and Dreamcast platforms. It is one of the first console games 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, as well as a Dreamcast VMU. All versions of the game are similar in quality and gameplay, although the online systems feature a mode to customize the players' own truck and use it online. The game is still online-capable on all systems except for PlayStation 2.
