I know it could just be a voice actor that has a similar voice to Nathan Fillion, but it does certainly sound like him.
It does kinda sound like him now that I concentrate on it.
Wow, never noticed that. You might be on to something.
It doesn’t sound like him to me.
if its buck… his gettin owned
I dont think that it is, kinda sounds like him but I am doubting it.I would love Buck to be in the game though, maybe as a S-IV
> if its buck… his gettin owned
I think everybody on the Infinity was.
Thats exactly what I was thinkin when I heard the voice!
I don’t know about that, but I do know the Grunt spoke English 
(if you listen carefully, he says “I see the Demon!”
hmm the weird thing is, why cortana knows its infinity, if she havent do nothing about 4 years and the ship is new

Right when the ship enters our view: “Mayday! Mayday! This is the captain of the UNSC Infinity! Blah blah blah taken control of our ship! Blah blah Forerunner world!”
One would think that it constantly broadcasts a signal so that other UNSC ships/personnel in the vicinity would know what ship it is. Also Cortana is a ship-controlling AI…surely she knows how to glean that sort of info from any sort of human transponder signal near instantaneously.
edit: plus what Dude said.

The Ship flew by them with the giant word INFINITE facing them. and if that isn’t enough tho convince you, the captain was hailing on the radio and said he was captain of the UNSC Infinite
what previous 2 posters said. I also wondered if she could hack the system and get all the data? No telling what tricks shes learned from gravemind and halo systems…
Unless there is a different voice actor now (which would be sad) then I can’t confirm it’s him. Similar though.
buck isnt going to be in halo 4 if thats what your speculating and i dont think he sounds anything like him.

The ironic part is that it’s called the INFINITY, not the INFINITE, so apparently it’s not enough to convince you
