What do the action buttons do?

In the bottom-right corner, you will see 5 buttons when you are walking. These are as follows:

• Shoot (Bullet icon)
• Aim (Target icon)
• Jump/Sprint (Person icon
• Swap (Pistol icon)
• Reload (Ammo icon)

Tapping the Shoot button fires your current weapon once. If you have an automatic weapon, you can hold this button to fire continuously. 

Tapping the Aim button will allow you to aim down the sight of the weapon to help with precision shooting. Note that you won't automatically lock onto targets while in this mode, and shooting will hit directly where the center dot is. Simply tap the button again to return to normal view.

Tapping the Jump/Sprint button will cause you to jump, allowing you to get up onto small ledges, etc. If you hold this button while walking, it will allow you to sprint. Note that sprinting consumes stamina, shown in the top-right corner. If this bar is empty, you will have to wait until it is full to sprint again.

The Swap button will cycle through your different weapon types.

Finally, the reload button allows you to reload your weapon whenever you want, as long as you don't have a full clip. Note that if you try to shoot with no ammo left in the clip, you will reload your weapon instead as long as you have more ammo to spare.

When you walk near a vehicle, you will see a new button appear just to the left of the jump button. Tapping this will allow you to enter the vehicle. You can tap this button again to exit the vehicle.

When you enter a vehicle, the buttons in the bottom-right corner will update to the following:

• Accelerate (Up Arrows icon)
• Reverse (Down Arrows icon)
• Drift (Sliding Car icon)
• Horn
• Shoot (Bullet icon)

The Accelerate and Reverse buttons will allow you to move forward and backwards relatively.

The Drift button will allow you to skid the vehicle, allowing sharper turns.

The Horn button will sound the vehicle's horn.

Finally, the Shoot button works the same way as described before.

Note that you are able to use the Joystick in the bottom-left corner to turn the vehicle left and right.
