In this map called Montana are two sticks of dynamite
in which i call them Nukes.  They have been modified
from their original style of dynamite.  You will find
one on the river and that looks like a normal stick 
of dynamite.  You will also find a stick in the 
bunker cave lying on the ground inside.  When you 
pick these up you have to push #1 to use them.  Then
you can lite it and throw it like a normal dynamite.  
But when it explodes you will see a difference and hear 
a difference.  So I would advise you to back far away 
from it because it explodes bigtime!  Thanx, LAW_Metallica
