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.)
Example:
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."
