Crossfire Extended Release is an extended version of Crossfire, a rogue-like 2D RPG, simulation, and graphical online chatroom. It features vast expanses and numerous cities, each with its own theme, deeply hidden worlds that very few ever venture to, flatworlds peeled off from the earth through hidden seas, and underground expanses. People can buy and build houses, towns, towers. There is a post office, banks, guilds. Boats one can own, castles one can rule over, forever, as a king. There is a weather simulation.
