Welcome to the game where in the goal is to kill off these guys with some form of pointy or shooty implement.
Monster Hunter is a series about hunting little things, making weapons and armor from the bits of the little things then eventually using those weapons and armor to hunt bigger things. Repeat until the next game in the series comes out.
There isa problem with the PC version. Make sure you have these codecs installed before you get to the final boss or the game will save right before an unwatchable cutscene which will make your game unplayable.
