Metal Gear Solid 4 - Extreme Big Boss Emblem Run - Act 3 Bike Chase & Raging Raven

My inexperience really showed in the beginning, it took me hours to develop my skills and get through this, it is a nightmarishly hard section, this is where you really earn your Big Boss Emblem... End Of Act 3 - 01:59:00 - Should be comfortably within 5 hours, may even break the 4 hour barrier...
