The SBP500 is one of the most powerful weapon in TimeSplitters Future Perfect. Its somewhat like a assault rifle considering its high penetration, accuracy, velocity, and how fast the bullets pour out. It's an Automatic weapon with a scope. It doesn't kill in an instant but does a very good amount of damage, and it also has a total load of 256 of ammo and each load of ammo used is 64 Bullets. But, it doesn't last long because it is an automatic weapon. This weapon is similar to the SBP90 Machinegun in TimeSplitters 2.
