Many new weapons. Monster combat followed ALMOST standard rules in 2017, with monsters spawning in front of the Booster Rockets each hour or when a symbol was successfully completed.

Although the game was still in its old java, desktop only version, it was still basically the Doubutt Game we know and love.
