Theoretically infinite, since no handheld, vehicle-mounted or ship-mounted weapon in the halo universe is capable of penetrating the armour of a space marine they'd have to wait until he died of starvation, which due to his enhanced physiology would take months.
That is assuming that he doesn't just jump underwater(where he can breath) and hunt for fish with his acid spit, ridiculous strength and super-spartan reflexes.
As a last resort they'd probably have to activate halo, which thanks to the hyper-advanced armour protection of the space marine would fail miserably.
The banshee is a flying machine in Halo Reach used to kill Spartans in multiplayer.
no, you cannot kill kat, but she can kill you. like she has to me, many times. note: the other spartans in halo reach cannot be killed by you.
to kill them
no
nothing
You can't kill the Sergeant on Outskirts because he is an important character to the game however you were able to kill him in Halo 1.
no only if the baby is deformed or weak
Personally i wouldn't kill marine animals, but some people will to get food or to have fun
All I know is that halo movie comes out next yeah (can't wait) along with halo 4 in the winter (also can't wait) and that bungie are sendin Microsoft and 343 indestries secret documents and that the planet master chief was heading to in the trailer is a forerunner planet and the forerunners created the halos to destroy the flood billions of years before and trains the first Spartans. Also halo 4 contains the halo reach multiplayer online and any kind of forge is not yet official.so yeah possible chief may come across forerunners and old Spartans which would be pretty cool. And the forerunners created the sentinels and used them to build there civilization then the flood invaded and they had to kill themselves to activate the halos and wipe the university whilst keeping two of every species alive . Hope this helps
