Killzone was a victim. A victim to a phrase that must have struck fear into the hearts of any developer back in 2004, a phrase that must have been the bane of any over-enthusiastic PR team and the cause of many headaches at Guerrilla games. Halo killer! Back in the mid noughties the game scene was settling in with the new king of console shooters, Xbox was taking off which was probably due to the Master Chief alone, and his second outing was on the horizon. Sony needed a competitor, something to quench the FPS thirst of its seventy million strong PS2 owners club.
