properly mourned, an elite Helghast battalion led by Radec mounts a surprise attack on the fleet, boarding or destroying several ships including the Sun. The ship's crew manages to evacuate, but Radec reaches the bridge and executes Jan and Evelyn, downloading the codes before they can be deleted. With the last of his strength, Jan maneuvers the ship to crash into the center of Helghan's Petrusite distribution grid, causing it to explode and disrupt the arc network. Seizing the opportunity, the survivors attempt to regroup, only to witness Visari detonate the warheads over Pyrrhus, destroying it and killing both the entire population and most of the remaining ISA forces. With ISA captain Jason Narville leading an offensive on the remnants of the Second Army, Alpha Squad breaches the palace, where they encounter Radec and the imperial guard.

Further interviews eventually revealed the trailer was indeed a "target render", a prerendered video showing the developer's goals for the finished product. At the Game Developers Conference in 2007, a Killzone
