Walkthrough - Act 4 - Shadow Moses - Underground Supply Tunnel

Patrol Zone[edit]

After a relatively brief cut scene, you're left to do battle with Vamp. Before you start you should equip only the syringe and rations in your items.  Set to alternate between the two.  Keep the ratios active as they will automatically refill your health incase it runs out.  You will need to switch to the syringe quickly when you get Vamps health down so be prepared to swap to it when needed.

This fight should be pretty quick as your attacks will deal considerable damage to the immortal, but note that his attacks are powerful against Snake as well. Also, from what we understand you can use whatever weapons you want against Vamp without ruining your no-kill run. Since he's immortal, he may not die anyway.

Still, we stuck to the Mk. 2 pistol and the Mosin Nagant, using mostly the pistol.  You can use any weapon you like. You will never actually kill him so this DOES NOT count as a kill.  Make sure you have one weapon selected and have being unarmed as your other quick selection.  You'll need to quickly switch to unarmed to perform the CQC with the syringe when his health is low.

For the start of the fight, just back away from Vamp as he walks toward you and hit him in the head with shots. When he gets near you, he'll stop and pose before dashing toward Snake with a quick melee attack. When he does this, put down your gun and run (or dive roll) perpendicularly to Vamp's path of travel.

Vamp abandons this attack pattern pretty early and moves onto running attacks. He won't stop to let you know he's going to attack, he just runs straight up to Snake and executes a spinning combo attack. Keep your gun firing on his chest and face as he runs up to you, but as soon as he gets real close you want to drop your aim and dive roll away. Don't dive before you're sure Vamp will attack, though, because Snake has some recovery lag on the maneuver and Vamp will take advantage if he isn't recovering himself.

There's no use trying to use CQC in the middle of the fight, so don't even try to grab or dive through Vamp. He'll eventually start jumping around while tossing knives, though his throws are pretty inaccurate and this pattern lets you pull out your gun and take some shots while he's away from you.
