What is "killzone"

Killzone is a first-person shooter, developed by Netherlands-based Guerrilla Games and released on November 2, 2004 in North America. The game was remastered in HD by Supermassive Games and re-released within the Killzone Trilogy for PlayStation 3 as well as a standalone PSN title on October 23, 2012.

Killzone takes place in the middle of the 24th century and chronicles the war between two human factions; the Vektans, and the Helghan. The game is played from a first-person view and follows Jan Templar, a high-ranking officer within the Interplanetary Strategic Alliance, as he battles invading Helghan forces into Vekta.

Prior to its release Killzone was heavily anticipated with several publications considering it to be Sony's " Halo killer" title. Upon release, however, the game was met with divided responses, with most critics praising Killzone's visuals, art design, soundtrack and atmosphere, but agreed that the final product was disappointing, with criticism also aimed at the game's narrative, characters and gameplay. Despite mixed reactions, Killzone spawned numerous sequels, several of which attained critical acclaim.
