How do I get more Slow-Mo?

When you have zero Slow-Mo left you will notice that the icon to activate Slow-Mo will no longer display the amount that you have left and this number will change to a Plus (+) symbol. Simply tap on the Slow-Mo button and you will be shown a pop-up menu that will allow you to purchase more Slow-Mo for in-game currency.

Alternatively, you can purchase more Slow-Mo from the main menu by tapping on the Cart button located in the top-righthand corner of the main menu.
