maybe we can make a good fight out of this by taking away Kains immunity to death
then at least Master chief and Turok would probably win what with Turoks nukes and such, altho hed prob end up killing MC in the process because i think the weapon only protects him from its power and maybe could kill Kain with it, altho Kain is fast and can go mist form which would annoy them alot as well as keep teleporting
altho i think even without his immunity they would lose because in an instant Kain can use telekenetic force to take their weapons
