Starhunt Game, located on Herta Space Station once you've reached Trailblaze Level 21, is unlocked during the Companion Mission named Punklorde Mentality. It involves two phases, Story Mode and Arcade Challenge, the former of which sees you collect and analyse different types of graffiti in order to unlock the Light Cone named Before the Tutorial Mission Starts. If you play during the Event period, then you can also unlock a currency named Always Smiling which can be traded in the Event store for resources, including items which can Superimpose the aforementioned Light Cone. Meanwhile, the Arcade Challenge consists of three phases: Hidden Codes, Access Screening, and Sealed Sector.
Hidden Codes are pieces of graffiti you need to discover around Herta Space Station in return for rewards. Access Screening, meanwhile, are objects you need to photograph. Finally, the Sealed Sector consists of four unique combat gauntlets, where you're able to discover Silver Wolf's calling cards in order to add a powerful attack to your arsenal each turn. There's a puzzle aspect to these challenges, as you need to discover graffiti in order to unlock doors and lower the level of some enemies.
