How to Get Polyboard in "Mobile Weapon" (Clarification Needed)

"Mobile Weapon" and "Polyboard" do not match any major released game in my database. This could be:

• Mobile Suit Gundam: "Polyboard" might refer to a material/part in Gundam Breaker, SD Gundam G Generation, or Mobile Suit Gundam UC.
• Mobile Legends: No item named Polyboard.
• MechWarrior / Battletech / Heavy Gear: Possible crafting component.
• Indie/Mod Project: "Mobile Weapon" is a generic term.

Please provide:

1. Full exact game title (store page / developer).
2. Platform (Steam, Android, iOS, Switch, etc.).
3. Context: Crafting material? Quest item? Mech part? Currency?

With the correct title, I can give exact farm locations, recipes, or shop vendors.
