This is a side-scrolling game resembling the classic MegaMan gameplay. In this game you have to play as Fireman and make your way through the various challenging levels confronting numerous enemies. Every level has a different mission and also different enemies, but you will come to know about it as you play the game! Just destroy all the enemies and proceed further to the exit door of the level, to advance to the next level. Good Luck and enjoy!
