Killzone Trilogy

Killzone was released for the PlayStation 2 in 2004. The game is set in an era of space colonization where the Helghast Empire has recovered from its defeat in the First Helghan War and launched a blitzkrieg against the outer Interplanetary Strategic Alliance (ISA) colony planet Vekta. Vekta's orbital Strategic Defense (S.D.) platforms failed during the initial assault, allowing the Helghast to land swarms of soldiers onto the surface and making it all the more difficult for the outnumbered ISA forces. Captain Jan Templar, the main protagonist, and his squad are called back to the base for reassignment, and are promptly sent to find the ISA operative Hakha and the key in his possession. During the course of the game, Templar meets other characters who assist him such as Shadow Marshal Luger (a female special operations assassin), a heavy weapons specialist Sergeant Rico Velasquez (a Helghast-hating soldier with an itchy trigger finger), and Colonel Hakha, a half-Helghast, half-Human spy.
