7. Metal Gear Regain Energy Drink
Metal Gear was once again crossed with a popular energy supplement in Japan with the Regain Energy Drink campaign.
Other tie-in promo items were cell phone screen cleaners and artwork with familiar Metal Gear characters. Snake himself got in on the action, appearing in the commercial for the drink, which is said to taste like Red Bull. At least it followed in the same vein as the Calorie Mate commercial?
