Konami announced today a set of passwords that should help extend the Metal Gear Solid 4 experience through three new weapons.

Using the password, players will be able to unlock the Mosin-Nagant, D.E (Long Barrel), and Mk.23 weapons. The respective passwords are mnsoymsyhn, deskyhstyl, and mekakorkkk.

To get the weapons, simply input the passwords in the EXTRA section of the title screen. In all cases, you'll need to have advanced in the game to the demo scene where Mk.II first appears.

Konami plans on unveiling more passwords in the future, possibly unlocking more than just weapons.
