Rockman Zero 2 offered a moderate difficulty level but Zero 3 is a bit more difficult to handle. The enemies and bosses are a tougher lot to crack but we're getting the hang of it. Controls in the game are standard with "A" making Zero jump and "B" blasting out a shot. Holding down "B" charges up the laser for destroying oncoming mechanical can with a single shot.
   In the beginning of the game, snow burrowing creatures dash around and then jump up and shoot at Zero while stationary snow turrets are of little challenge. Zero later enters an installation and eventually battles a tough boss named Omega which shoots out laser rings and reflecting shots.
