These are strategies for beating the bosses to each world:
Prehistory - Bear:
Equip your large club and, this only works if he's on all four
legs, whack him in the head. Switch to a lighter weapon and dodge
backward until you're out out of his range. Wait 10 seconds for him to
cool off, then repeat about 4 times.
Roman - Bull:
Arm your axe and wait for him to charge you. When he's about 2
seconds away from hitting you, use your forward attack. Repeat this
process about 4 times.
Japan - Dragon:
Evade his his fireballs and slash his neck when he rears his head
back. Repeat until he is dead.
European Middle Ages - Demon:
You can use the Magic Spell but I recommend the crossbow. Shoot
at him when he stops moving, but be sure to avoid his projectiles.
Grab the nearby battery if you need extra health.
Conquistador - Aztec King:
This guy is a piece of cake. Shoot him 3 times with the pistol.
Be sure to reload before he can get near you.
There really isn't a boss here, just a lot of guys shooting at
you at once. Use lots of dynamite and shotgun ammo.
Modern Wars - Tank:
Pretty strait forward, use the bazooka. Its machine gun attack is
impossible to avoid, but you can dodge its missiles.
Future - Cyborg Alien:
This guy is a nasty little sucker! The only weapon that even
dents him is a thermal grenade, so make sure you have a lot. Be sure
to avoid its lasers, and don't let it get too close.
Beyond Time - The Virus:
The virus is very fast, so don't unload all your ammo at once.
Wait until he is fairly close and isn't moving too fast, then nail him
with a crystal. He doesn't do a lot of damage, but if he hits Betty,
you will get hurt. Note that you can move vertically in this arena.
