With Leon and Claire dealt with (or incapacitated, depending on your choices), your final objective is to extract from Raccoon City as the government initiates its 'Sterilization Protocol.' The city is now in utter chaos, with military airstrikes and widespread destruction. The path to extraction will be a desperate dash through burning streets and collapsing buildings.
You'll face a final gauntlet of all enemy types encountered throughout the game, including multiple Tyrants, G-Adults, and hordes of infected. Ammo and health will be extremely scarce. Focus on survival and reaching the extraction point. The final extraction zone will be a heavily contested area, requiring you to defend against overwhelming odds until your transport arrives. This is the ultimate test of your team's endurance and skill, concluding the main campaign.
