As seen on Clickgamer Handy Entertainment has released Psych Path 2.

Annihiliate those annoying little fellows on a busy road. Give it twists and turns in the ultimately futile efforts to scratch your PDA screen. Launching Psycho Path is like a reward at the end of a hard day. Something that takes out aggression, releives stress and puts a smile on your face.
