Double Credits (Asphalt 8)

Introduction
The Double Credits is a powerup in Asphalt 8: Airborne, which doubles the amount of Credits earned in a race. As with other boosts the Double Credits powerup is effective a certain time during which all the races a player starts are affected.

Usage
The Double Credits can be used before the race using a powerup selection before starting a race (if you don't have one, it costs ? to activate one unit). Each unit lasts about ? hours. During this period, the the amount of Credits earned in a race will be doubled. The Double Credits powerup can be replenished by winning cups or finishing certain collections.

If the Double Credits boost is activated, a boost icon will appear in the main menu along with a timer indicating how long the boost will last. A timer will also appear on the Boosts-screen indicating the remaining time of the activated boost.

Trivia

 * In earlier stages of the game (around February 2014, pre Great Wall update era), the Double Credits powerups received as trophys in the Time-Limited Events lasted for 24 hours. At that time the Tuning Kit would last for 8 hours, Extra Tank for 4 hours and Nitro Starter for 2 hours.
