Goals & Pillars:

  • Recognizable elements that make fans say, “Yes, this is Monster Jam!”
  • A game that’s easy to pick up and play
  • More fantasy, less reality: what can’t Monster Trucks do in real life?

What I accomplished:

  • Designer on project from inception to game’s world wide launch completion
  • Led small prototyping team to prove out a fun gameplay that met stakeholders’ project pillars & goals (listed above)
  • Soft launched MVP (minimal viable product) of the game within 5 months to meet stakeholder deadlines
  • Continued designing and polishing gameplay, setting design pillars for creating new trucks and creating levels
  • Conducted 15+ internal and external in-person playtests including using services such as Playtest Cloud
  • Helped the Producer grow the team allowing us to scale up content for live ops production
