GamePro played a new, never-before-seen demo of MGS4 on the show floor of E for All.
New details in a nutshell:
* Pausing the game brings up the minimap with a full-fledged waypoint system.
* The threat ring that surrounds Snake replaces the radar system from previous games, and increases in wavelength when a threat is nearby.
* Enemy APC vehicles are equipped with a 360-degree security camera.
* Smokes return in the inventory.
