Contra III: The Alien Wars Cheats (Wii)

During a game press & hold START & SELECT.

When playing co-op mode, after losing all of your lives, you can press X + A to steal a
life from your life-hoarding partner.  Try to use your stolen lives to immediately fall
down pits or get shot by a slow, obvious bullet.  That'll show 'em!  Who's the better
player NOW!

To get the secret gun, make sure the difficulty is on normal or hard. Play

until you get to the sixth stage. When you get to the final boss, it will

have different shapes going around it. Try to shoot the one that looks like

a spike. It will drop lots of guns and bombs. Get under the boss and wait

until the gun "M" pops out. It is the strongest gun in the game. It stands

for Mini Gun.

At the halfway point in the 3rd level, where the ship alternates between dropping grenades
and soldiers, stand all the way to the left and aim your gun to the right (You might want
a turbo controller for this one). Fire to the right and leave the game running. If you
leave and come back atleast a half hour later, you should have 30 lives on the counter.
