A pitching game where the pitcher is you.
TopV Unleash is a 3D baseball pitching and hitting game inside the TopVelocity Player Portal. Most baseball games hand you a made-up player with made-up ratings. TopV Unleash uses the numbers you train with.
Your fastball comes in at your velocity with your spin and break, from your PitchDNA. Your windup is your own MechanicsDNA delivery. Every pitch is broken down the way your bullpens are: spin, spin efficiency, vertical and horizontal break, extension, and how far you missed your spot.
No test yet? You start from your level's typical numbers, and the game rebuilds you after you test.

What is TopV Unleash?
