yeah it is more of a slash than a stab, and if it is halo 2,
they uppercut!
@lethalgeek--I think you mean the energy sword? It's more of
a slash.
I like arbiter better, that sword man.. *stab* *dead*
you can survive hundreds of gunshots but one stab, dead.
I like the Arbiter more, but yes, MC kicks mucho asso.
master chief kicks so mucho asso
