There are various objects on the map that can give you an advantage in battle.
Boost zones can be used to double your car's speed for some time. It's a great way to outrun your pursuers or reduce the distance between you and an enemy. Boost zones become inactive after use and take time to recharge.
Portals take you to another place on the map. You can use them when you need to escape the battle or find a way to join your teammates in an instant.
The energy shield blocks damage. You cannot shoot when you are inside the shield and your enemy is outside the shield, and vice versa. Have problems with HP? - it's time to head to the shield!
