Operation Overstrike

Operation Overstrike
Operation Overstrike is quite similar to Operation Deliverance in the sense that new troops are being transported to fight off the Chimera. Two squadrons of British soldiers under the command of Steven Cartwright and Rachel Parker, would fly over Rotterdam to reach the Maquis stronghold in Luxembourg. They would then prepare the plans for the attack on the Paris Tower, hoping that its destruction would result in the destruction of every tower spread across Western Europe. Along with the Maquis forces, the first squadron of British soldiers is ambushed by Gun Towers when they reach Rotterdam, which leads James Grayson to say that Operation Overstrike is 'off to a piss-poor start'.

When the towers are destroyed and Rachel Parker's squadron arrives in Rotterdam, the British troops travel to the Maquis stronghold in Luxembourg. Unfortunately, the Chimera have already discovered the stronghold and dispatch multiple Earth Movers to take down the fortress. The Earth Movers are stopped by Cartwright and Grayson, but their victory is overshadowed by an all-out Chimeran assault on the fortress in Luxembourg. Claude Bouchard along with his daughter Raine Bouchard were still busy developing the serum that would kill the Carriers and supposedly put an end to the Chimeran conversion process. While the British marines and Maquis forces are desperately fighting the Chimera in the trenches, the refugees are being evacuated by VTOL aircrafts. Grayson is tasked with saving Raine and Claude Bouchard, but they both refuse to leave for as long as the serum is incomplete. Claude is killed by a Burrower, and Raine completes her father's work. After saving Raine from the attacking Chimera, Grayson proceeds to help fend off the Chimera in the trenches while the refugees are being evacuated. When the VTOL carrying Roland Mallery and Raine Bouchard is hit, their nav unit is badly damaged, rendering them unable to fly the aircraft. Cartwright then collects a new nav unit from a destroyed VTOL and delivers it to Mallery's aircraft. The VTOL lifts off and is headed towards Reims, the only safe place left for the Maquis forces. Soon after, Rachel Parker arrives in another VTOL and takes off with James Grayson and Steven Cartwright.

In Reims, the plans for the assault on the Paris Tower were finalized, and Steven Cartwright leads the battle. Their goal is not only to destroy the tower, but also to distract the Chimera while James Grayson attempts to reach the Chrysalis Lair to infect the Carriers with Raine Bouchard's serum. Both goals were reached, although not without a grave amount of casualties on the human side. Throughout the catacombs in Paris and the Chrysalis Lair, the player can occasionally hear orders from Cartwright towards his troops. He mentions that this diversion will not last forever due to the many casualties, and hopes that Grayson has already made it through Paris.

Operation Overstrike was a success, liberating Western Europe. Poland and Spain were still occupied by the Chimeran war machine, but after Operation Overstrike these countries became the main battlefields within Europe.
