FIFE stands for Flexible Isometric Fallout-like Engine and is an open source project for the creation of cross platform ISO/top-down 2D games (e.g. RPGs & RTS'). The assets of Interplay's RPG classics Fallout 1 & 2 are supported as test implementation but are not required to work with FIFE. It is not a Fallout emulator and you cannot play Fallout with it. The project's goal is more universial. You can read graphics from fallout data files and create your own mods or draw you own content and make a completely new game.
