DUDE ITS TOTALLY ok..
there is no swearing in game in i think.
but the community is about the same.
most people from halo went to cod4
because cod4 prwns halo.
known fact.
cod4 bought out the best in a fps game.
my freind who loves halo to the bone and denied for so long that halo was better then cod4.
but the second he got cod4 like 2 years after it came out.
he was like omg, and got hooked on to it.
so yah halo and cod4 are simlar but you have a much better expeince on cod4 because of it realism and community is more mature and i tell you this they are more helpful and the game mods are totally better.
its hard to say because halo is good, but once you play the cod4 storymode your be like omg.
the sniper level was the best.
halo good story mode, but medicore these days.
so i suggest you try it.
as for violence, just watch out for english vs americans, your see a lot of team killing when conflcits arise, and they arise alot lol in cod4 its like a major thing.
because british troops and american troops and iraqis are in it so alot of talk goes on in the game.
but yah i givin you reasons why to play it and what to expect!
but sometimes, you get people that flame young kids, but you dont see so many as like in halo, so people are helpful on cod4, doe its really competive and that is what makes the game fun, just so cool.
and cod5 is even better online, at one area and that is bigger maps and vechicles online.
cod4 doesnt have cars in it so its all tactical so you dont have noob shield or med packs just red screen and limited ammo.
but you get rewarded ingame and have you perks , so if you get 7 kills you can call in a helicopter to kill the other team or if you get 3 kills you can call in a airstike.
and with perks you can custormise your character so, have abit extra health or stronger bullets or deeper penatation so bullets go though more walls.
and not to mention claymores you can set traps and be a sniper and wait for the bait when playing search and destory.
and then you got hardcore gameplay modes, for the ones who think they are experts.
and then teh more you level your person up the more gameplay modes you unlock.
so really its your choice if you want to play it or not.
