XtremeIsland is a single player game where you are transported to an empty world where all you have is a tiny island and a meager set of supplies to survive. Challenges may be completed for additional resources and your overall score is tracked realtime against other players. You get one chance to expand your island score as high as possible before falling prey to clumsiness or the dangers of a ruthless world. The difficulty is hard and natural health recovery is disabled. If you die, it's all over. Your island is removed and your score reset.
XtremeIsland is built against the latest 1.2.1-SNAPSHOT of canarymod and supports Minecraft 1.8.
