Dungeon999F is a seemingly endless game which provides hours of fun! While it seems like the game doesn’t have any end, you can see the finish line in the end – after 999 floors. You are a one man army – Jack, the Black Hair, and your only mission is to fight against enemies and reach the end. Your enemies are slimes which have rebelled and you have to find out why. And the answer is hiding on the 999th floor!
