Over 50 Combine soldiers and attack vehicles were crossing the bridge they had used to transport Advisors, the one that Gordon and Alyx saw a few hours ago. They were heading to their base to reinforce assault attacks on White Forest, this time they would overwhelm them from all sides with both ground and air attacks nonstop. Just as half the force was in the middle of the bridge, one of them spotted two flying objects in the air, "What the?" It soon caught the attention of everyone. At top speed it was two F-16 Fighting Falcons, but by the time the Combine realized that, it was too late, they had already fired four missiles at them which completely destroyed the bridge and anyone who hadn't been killed in the blast fell too their deaths as it collapsed. Remaining Combine who weren't on the overpass were cut down by guided rockets and chain-gun fire from AH-64 Apache helicopters.

Previous places that Gordon and Alyx had been too since escaping City 17, the Combine tried to take back and establish new bases, but like what happen on the bridge, unknown forces were wiping them out. The small abandon town where Gordon and Alyx were attacked, Combine soldiers returned and tried to restore the force field to stop any reminding rebels from reaching White Forest. But the small town and the Combine were wiped out by air bombings. Many Combine soldiers were being killed and there bases were being destroyed. Many by tank and air attacks, others from long-range snipers and several by stealth strike teams. Some Combine didn't know it at the time, but they were now fighting two wars, the rebels and this new unknown force that had better technology, manpower, firepower, with people who had far better combat warfare skills and experience. The Combine were not use to these type of attacks and there commutations was in disarray, each base and group had almost no way of warning others.

Some areas were filled with nothing but battles in the sky as dozens of Combine helicopters took on dozens of Apache helicopters, but because of their numbers and firepower the Apaches were the victors. Even the Striders couldn't withstand dozens of Apaches, F-16's and other Jet fighters and bombers. But the Combine weren't the only ones being wiped out, places where there were overwhelming Zombies were now entirely deserted such as Ravenholm. Other places where were either bombed or burned down with flamethrowers. It seemed as if this new force was performing a Scorched Earth strategy, but they and there reconnaissance group did it's best to make sure that no innocent people were killed in the process of there attacks. They even found and gave shelter and protection to several refuges.

Unknown location
