1) An area of terrain that is well defended, creating a killing ground for enemy troops

2) A good FPS game for PS2, that should not be compared to Halo as they are too dissimilar in style to be compared effectively. Halo takes a vastly different approach to the space opera genre to Killzone. While Halo decided to focus on fast-paced human vs alien combat with exotic weaponry, Killzone was designed to be a brutal and gritty human civil war in space, and it succeeds in creating a dark, post-apocalyptic atmosphere which is exciting, dramatic and thrilling in its own way.

i.e. stop saying that Killzone was/wasn't a halo-beater and just have fun!

1- A military term describing an area of ground that is well defended, possibly including pre-sighted machine guns, mortars, artillery, as well as a variety of obstacles such as razor wire and tripflares. (Weapons will be presighted to these obstacles, as approaching troops will get caught in them, making them ideal targets.) This creates a literal "killing zone," hence the name.

2- A recent FPS for the playstation 2. A decent game that can be accurately described as "Call of duty in space." This fun and well-rounded (although linear) game is unfortunate enough to have been over-hyped as a "Halo-killer" which is nothing more than a kiss of death, as now everyone, especially reviewers, will try to campare it to Halo, and of course, find this game lacking.
(And yes, I've played killzone. It's good, but not to the scale of Halo.)
1- "With our platoon support weapons pre-sighted to these tripflares, we've created a fairly night-effective killzone."

2- "Killzone's no Halo-Killer, but it's still a really good game."

the game that rapes the craptastic halo series. killzone replaces pink aliens with horrifying helghast with red glowing eyes. it's hated by many who have not seen the light of what a console fps should be, but the experience of killzone completely oblatirates the ignorance of halo fags everywhere.
n00b: OMG i'm gonna play halo with my shitty plasma weapons and pink aliens

Well-Educated PS2 Owner: i'm going to throw knives at people's throats and rip them out, then cook a grenade and throw it at a horde of men, and then hide in the bushes. why do i do it? because i can't do that in halo, and i don't want to play online where everybody sounds the same.

a great, but somewhat hard fps for playstation 2.
Yes, I've played it. I have it.

Fun game with weak, completely outdated weapons.
The first killzone would have been much better had they ironed out some minor issues. I wish they would just set the series in 2025 if they are going to make the weapons so similar to today's.

a game that seems badass the first what... five minutes, it quickly turns into a complete gayfest when the other craptastic characters show up, they don't die, you do, there's no point to covering their asses even when ur on the hardest difficulty. The firing mechanics will ruin the way you play real first person shooters (just go sniping in this game) I guess it would be great online, except no one plays the playstation online crap cuz xbox live pwns it into next century, and playstation online is free... this was supposed to a halo killer, seriously this game still sucks compared to halo 1, and that came out like three years before this bullcrap, i have both games and i have to say this game really sucks and it pisses everything off... epic fail... also see goatse for an even more dumbed down definition.

guy who owns both consoles: fail, none of this crap minus the cooking grenades part ever really happens in killzone... the bushes sometimes happen online, but only if ur ass can find someone to play, and if the bushes are of any use, halo on the other hand, you can do almost everything this guy mentioned, and who needs to cook a grenade when you can stick crap on people, and the plasma sword... awesome, y would u even throw that?
