Metal Gear Cheats

When fighting the Bull-Tank you can reset its position by accessing your Sub-menu. This comes in handy if it gets too close, due to it having a 1-touch kill on you. To defeat it, use your Grenade Launcher.

In the areas where the black holes quickly open up to swallow you just simply pause the game and unpause. When you return to game play the holes will be frozen in the state of expansion they were in when you paused. They will be invisible but smaller. Simply side step around where you saw them last and you will be in the clear.
