Well, while This thing tears me to bits, I might as well tell you about the drones.
Name: Dx4 mech
Weapons: bladed legs
Bio: The Dx4 or ninja drone, as some may call it, is built for speed, stealth, and most of all, assassination. this drone is almost impossible to spot in it's normal mission hours, as it attacks mostly at night. It's three legs end in razor sharp blades. it's only known weakness is it's lack of armor. if you were to see one before it sees you, you might just be able to take it down in one to two hits with most conventional energy of projectile weapons. If you see one do not try to attack unless you are an experienced toa; just stay low and wait for it to go away.
Now for the next one.
Name: Juggernaut MK IV assault mech
Weapons: Rotory cannon
Bio: The Juggernaut is a heavily armored drone. Most conventional weapons wont work against it's thick armor plating. The only discovered weak spot is on the 'neck' of the cannon. the best strategy for taking on this drone is to run around it, as it is quite slow, and place an explosive charge on the back of the 'neck'.
I have one more to tell you about.
Name: Dx7 jungle variant
Weapons: bladed legs, energy cannon, small pulse blasters
Bio: This drone is a variant of a design similar to that of the Dx4. It is designed for jungle combat. Unlike the other drones, the Dx7 does not have a finite power source. it is solar powered. the most effective way to defeat this drone is to either lure it into a dark place and keep it there for about 10 minutes to tire it out, or to just plainly smash the transparent solar panels located on the sides and legs.
