Overview:
Killzone 2 is said to take place (at least partly) on the Helghast home planet of Helghan- shifting from teh ISA colony palnet of Vektra featured entirely in the two previous games. The media released by Guerilla Games thus far depicts an ISA orbital invasion using drop ships carring ISA infantry down to the Helghast capital city of Pyrrhus (despite heavy Anti-Aircraft fire) on the planet's surface. It is still unknown whether this is a full scale invasion intended to occupy Helghan completely or merely a retaliatory strike by the ISA for the events that took place on Vektra during the Helghast invasion. The media released depicts street battles and heavy resistance by the Helghast defenders.
