halo and halo2

Then all you need is a single SMG bullet to finish you off, because it has happened to me numerous times.

I'm pretty sure using a gun wouldn't qualify as killing them with just grenades.

Which is another reason why Halo > Halo 2.

I'm going to experiment with this, because I may just be mistaken and maybe two of their teammates are throwing greands and they are exploding at once to kill me then. I don't know.

It's true a single frag can't kill you if you have full shields. So there's some other contributing factor.

It is not possible to kill someone with a fragmentation grenade if they have full shields. I guess maybe if you bounced it just right and it blew up right in their face it might kill them, but I'm pretty sure it isn't possible.
