Resources

Ro-Bucks
Ro-Bucks are used to buy capsules in the shop to get perks that are used in a match. Ro-bucks are also used to buy backgrounds and nametags for your profile in the game.

Crystals
Crystals are used for the tower gacha, featured towers and featured perks of the day. Crystals can also be exchanged for scrap metal, another currency in the game that can be used to craft capsules.

Scrap Metal
Scrap Metal is another currency in the game that can only be earned from Bounties or exchanging gems. Scrap Metal is used to make capsules instead of buying them with Ro-Bucks.

Trophies
Trophies are earned from PvP or Tournaments to get Legendary tier towers and perks that can only be bought from the Salesman in the PvP section in the lobby.

XP/Experience Points
XP is the currency that is used to level up. Levelling Up contains a small reward of Ro-Bucks. When you get to level 10, the game allows you to do Bounties and gives you your fifth tower slot.
