Tree Upgrades

The tree upgrades are unlocked at x40 Stars in Scrap Clicker 2 and only exist in that one game. They're several upgrades, but all are maxed out after purchasing just one level, making them different than the other upgrades. Not all upgrades are instantly unlocked, only some are unlocked at x40 stars, the others are locked until some stars later than the last ones each.

They can be brought using several ressources, like Star Fragments, Magnets, Golden Scrap, Steel Beams or Wrenches.

Trivia

 * The upgrades of the stars x40-x100 cost 2205 Fragments, 30000 Magnets, 335.000.000 golden scrap and 5175 beams.
