Re: How about this sci-fi battle..
Isn't that the title of the latest Street Fighter game?
If you have read the comics or played any of the video games, we see the Predators purposely limit themselves in what they use as sort of a "right of passage".
Examples:
PREDATOR: Predator takes out Jesse Ventura with the Plasma Thrower as Jesse has a big ass gun. He takes out Hawkins (glasses) and others with his wrist blades as the have small calibre weapons or knives (Billy tried with a knife). Now this was an experienced Predator out on a solo hunting trip.
PREDATOR 2: Less experienced Predator out with a hunting group and more dependent on his gadgets. He used the netgun, spear, dart-gun and disc to dispatch foes.
Predator comics: When dealing with Aliens, they are usually much better armed and armored. They wear their own version of plate mail and have hand -held as well as shoulder mounted version of the Plasma caster. The have longer bladed weapons to keep them at a distance from Aliens.
