Rockstar’s Leonida postcards make a good spoiler-free preview
Rockstar’s downloadable artwork includes postcards for Vice City, Leonida Keys, Port Gellhorn, Ambrosia, Grassrivers and Mount Kalaga National Park. The format makes it easy to get a quick visual introduction to the regions without sitting through a story trailer.
The artwork library lists multiple sizes for the postcards. Choose one close to your screen shape. For a vertical crop, preview it on your lock screen so the clock and notifications leave the main subject visible.
