On Horizon Zero Dawn and the Frozen Wilds expansion I designed the entire global game economy. This included the entire player progression arc from the start of the game until the finale, including the entire loot tree for all enemies and robots. Additionally I was responsible for the design of all shops, crafting, player inventory and the trading system. I was also charged with the entire suite of inventory items spanning the ~70+ hour campaign. Core implementation consisted of extensive nodegraph work in the Decima engine as well as level design and some of the supporting UI assets.
