The Berserker Splitter is the only TimeSplitter to appear in Future Perfect. They attack by releasing bolts of energy that track their enemies. They are similar to their Reaper Splitter cousins in many ways, but they tend to walk on all fours rather than upright like the Reaper Splitter, and they have a more reddish hue, in stark contrast to the Reaper Splitter's pale white skin. Also, they walk to get to places, while the Reaper Splitters can teleport to areas instantly. The beserker splitter appears in the opening movie for TSFP and is seen drinking the blood of a fallen soldior. It looks up to see cortez's ship before going back to its drink.
