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!

A large tank-like vehicle, only with legs rather than tracks, ergo the name "Walker"
Walkers are not humanoid in design and should not be confused with mech
A walker can have any number of legs from 2 upwards
"Imperial Walkers!" -referring to the AT-ATs of Star Wars fame
