OK so I read some of the reviews and thought to myself "none of these give a complete picture" Halo is a vast universe of games movies and comic books, its full of sacrifice, secrets, and heroes, one review can't hold the huge amount of information on this subject, I would recommend checking out halo wiki for more info. Let me just clarify a couple facts covered in this article, the covenant is not some crazed alien race out to destroy earth, that's only part of it, the covenant's government is run by self proclaimed "prophets" they've banded together several alien species to aid in finding ancient "Forerunner" technology, the Forerunners were a race long before humans who controlled most of the galaxy, their empire was prosperous and grand, until they ran into a alien parasite known as " the FLOOD" the flood is a creature that consumes living organisms and and turns them into a zombie like state, the forerunners fought a long war with this creature, but after losing so much, they decided the only way to destroy the flood was to take away its only life force, so they built huge ring worlds known as Halos, these were built to self destruct and destroy all life in the galaxy therefor starving the flood of its life force, their plan was to activate the rings from a safe location and then reseed the galaxy, sadly this never happened, the rings activated, but the forerunners were never seen again. now the covenant "prophets" believe that the forerunners built the ring as a portal to elevate themselves to a god like status, so they've made the entire point of their religion looking for these rings in order to start "the great journey" but when they finally run into humanity in the year 2525 the prophets soon learn the error of their ways, instead of admitting their mistake the decide to cover it up bye declaring that humanity is an affront to the gods and must be destroyed, or else "the great journey" won't happen, this sends the military into a blind rage, they attack our planets with with extreme force, we don't stand a chance against their advanced technology. that's what the game centers around, that's why were fighting, O.D.S.T or Orbital Drop Shock Troopers, are a brave group of soldiers who more or less sky dive out of ships orbiting the planet, they land in key locations, to help in special operations, what do you think good role models? and seriously since when is blood violent? its inside you right now, if your child doesn't know about blood their gonna be in for a huge shock, oh its just killing aliens! hurray death of other species! language shouldn't be an issue trust me try theirs way worse at school, kids drop F*** bombs all the time, over all this is a great game most kids just want this for the forge any way, although I wouldn't recommend voice chat on Xbox live for any one under 14 though.
