'''Bolts''' are the in-game currency to buy upgrades in the [[Game Modes|Endless game mode]]. During every stage, you can get three bolts. Every time you make it into the next station you get a bolt. If you complete the [[Missions|mission]] given to you at the start of the new stage, you will get a bolt. The last bolt is always hidden somewhere in the stage. | '''Bolts''' are the in-game currency to buy upgrades in the [[Game Modes|Endless game mode]]. During every stage, you can get three bolts.
