Bunker Buster

The level Bunker Buster takes place immediately after the previous level, Spectre. Your objective is to retrieve specific documents while planting C4 in specific areas.

Summary
After the AC-130H Spectre softens up the last bunker, you assume the role of Bravo 9 as your squad infiltrates the base. You start off facing a door which your fellow teammates blow open. Get ready for some intense combat, as Ultranationalists dot every room and corridor (many wielding shotguns, so watch out!). You are tasked to retrieve different documents from specific places while planting C4 in various places. After all of those is done, prepare to make a break for it. The C4 you planted will begin a countdown, so you have to get out of there quickly before the base blows up. You will encounter many enemy troops along the way, so take care of them quickly. The area will shake more violently every passing second. The level ends when you successfully reach the extraction point before the countdown ends.

Trivia

 * An easter egg can be found on this level. It is simply a room with a shooting range (similar to F.N.G.).  In it are various types of guns you can acquire, such as an M16 or an AK-47.  Its purpose is unknown.
