Blaster Master Cheats (Wii)

After killing the large mutant that is blocking your way, and the Plutonium Boss appears,
try to trap him in the top right corner of the screen and blast him with all the grenades
and gunshots you can fire. He may hit you once, twice, or three times, but you will hit
him many more times than that. The hint works since almost 100% of the time he is in the
corner. He cant aim his whip diagonally, making it almost perfectly safe to defeat him
without getting killed. This may require a little practice.

To easily defeat the bosses for levels 2, 4, 6 and 7, throw a grenade at them. When they
begin flashing after being hit, pause the game. While the game is paused, the bosses will
keep suffering damage as they flash. If you wait long enough, one grenade can be used to
kill the bosses.
