• Unless you are going for Rank 1 or Big Boss, you want to farm alerts in the Dock.

• There are many possible variants to the Dock, but only one thing is required. You must alter right guard's path, or kill him. If you do not, you will not be able to get on the elevator quickly (assuming stealth).

• If you alter the left guard's path, you must alter it further or kill him. Unaltered, he leaves the elevator area just before the elevator arrives (assuming stealth).

• You can use the credits as visual cues for stealth. Head up the left path when CG Artists Takashi Mizutani and Hideki Sasaki appear. The final credit is Assistant Director Yoshikazu Matsuhana.

• Instead of knocking on the wall, you can let the elevator guard exit. This is slower.

• Initial dpad movement is simple and the same on every difficulty to manipulate the Helipad guard

• Quick equip Chaff on Heliport Pickup if you performed RAM Manipulation

• Stealthy position at the searchlights

• If you do not hold up on the analog for the Miller call, Snake will stop crawling. Be sure to move forward on the analog stick at the end of the call, so you won't stop. Feel free to switch to Dpad afterwards if you prefer.

• Once out of the vent, stand up quickly by pressing triangle and X shortly after another. This will skip the stand up animation play out.

• As you approach the DARPA Chief vent, mash circle to enter the vent as early as possible (Vermillion Vent)

• Quick equip Card in Cell if you performed RAM Manipulation
