G.I. Joe: The Rise of Cobra

This trophy is simple. There are three Point Multipliers: 2x, 3x, and 5x. Point multipliers are awarded when a player does well without taking damage. Simply take your time and shoot enemies from a distance, dodging fire at all times. If you see a x3 multiplier spawn, then you are close to getting the x5. Go Joe (use accelerator suit) to help kill more enemies without taking damage.
