Killzone

They developed a passionate hatred for mankind, and eventually formed the Helghast Empire, attacking the planet Vekta controlled by the Interplanetary Strategic Alliance (ISA).

As Helghast soldiers invade the planet's perimeter, the ISA forces are trying to hold the ground and find a way to stop them.

Killzone is a sci-fi-themed first-person shooter.

The game's stand-out feature is the ability to control any of the four different protagonists, each with his or her own strengths and weaknesses.

These characters are: Templar, the balanced squad leader; Rico, who prefers heavy weaponry and is on a quest for revenge; Luger, the team's only female member and a specialist in stealth, who can access special areas; and Hakha, a half-Helghast who can use Helghast weapons and proximity mines.

Up to sixteen players could compete in the online multiplayer portion, which includes eight maps and six modes: Deathmatch, Team Deathmatch, Assault, Defend and Destroy, Supply Drop, and Domination.

The online servers of the game have now been closed down.

Killzone for PlayStation 2 is currently worth €10.57 loose, €7.39 complete in box, and €57.31 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Killzone has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Killzone, loose is €10.57 and CIB is €7.39 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Killzone is currently worth €10.57 loose, versus €8.71 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
