Please help me i've tryed and tryed but i can't seem to find out how you beat stinger i'm not sure if i have to just keep shooting him or what weapons are best for beating him... please help me out if you do know how to beat him e-mail me at Skrat113@aol.com thank you...

This has been awhile and no one is probly going to read this but I will post anyway.

Final mission is easy and short if you use these.. get the fastest human legs available,+ lightest core and decent boosters. The reason for this is you have to straff and boost without flying. (you could fly but i find it harder to dodge the billion energy beams in the air)
anyway outfit the AC with one of the 3 following weapons and your good. Karasawa (might want a magazine depending how your accuracy is)
or use the machine gun you get for beating Necron the top AC in the arena, that gun will easily tear Stinger apart.
And my final suggestion is use the twin grenade arms bring magazines if you can.
The basic stratagy for this is as soon as the fight starts straff circles around him will fireing. Boost only if needed. And when he starts the billion energy beam attacks just simply straff at walking speed and you should be set nicely between the attacks.
As long as you keep firing non-stop the fight will be over before he can do any real damage.

Moonlight saber is also good if you can cast the beam with it.
