Additional Unlockables

Metal Gear Solid 4 Guide - Additional Unlockables

Some unlockables have already been covered on our skills/unlockables page in the Metal Gear Online part of this guide, here are some more...

Non-lethality:

There are various unlockables that you need to complete the game with no kills in order to get. Use the Mk. II, Shotguns with V-Ring ammunition (from Drebin) or the Mosin-Nagant to tranquilise enemies, or of course non-lethal CQC. Everything in the game can be taken out with these, no matter how futile it logically seems.

Additional Unlockables:
