A weapon based on the real-life P90. The TimeSplitters 2 rendition is reknowned for its closer resemblance to the actual P90 than those in other games. The SBP90 has a magazine size of 64, and spits them out with a very high rate of fire and minimal recoil. It has a very long range scope, which is unique in the fact that unlike those on sniper rifles it does not give you the view from the scope. Instead, when zoomed in, the player's view point is moved closer to and then past the gun focusing on the crosshairs, with the screen becoming increasingly blue-tinted and full of static the further in you are zoomed, simulating the effects of the electronic scope.

Like most other weapons in TimeSplitters 2, it can be dual-wielded.
