Below is a short summary of the new information contained in the magazine:
- The game is set in 2008
- It seems that Niko always wears a helmet when riding a motorcycle
- When getting in a car, you now press two buttons to begin driving - one to get in, and one to start the engine
- In some cars you'll find useful items, such as money or a weapon.
- You can still get "wasted" and just like old time you'll respawn at the nearest hospital, minus your weapons and a little cash
- Bullet holes in vehicles and buildings won't disappear immediately
