To beat the final boss very quick, the first weapon you should use is the machine gun. It fires very fast and takes lots of damage. You should take about 1/3 or 1/2 health, depending on your accuracy. then get the pistols out while constantly dodging the blows of the boss. His health really wanes down with the flamethrower, but it sacrifices accuracy for power. When his health is down to the final count, slash away!!!!!

To get the C4 Hamsters, beat the Advance Training on the top floor of the Museum.
