(Usually runnes do not pick up claymores for a full game)
There's a new method using Claymores in the Mantis fight.
We can use a Claymore on a precise spot with a precise timing (when he lands on the ground)
and it allows to end first phase after 2 shots on EZ instead of 7 shots using grenade.
We can force him to land on the ground to use Claymore faster by skipping chairs phase
but it requires a frame perfect shot which is pretty tricky.

once through the door, use GME Phase 2
The PC speedrun can use the god mode exploit at the start of the fight for an even faster time to finish the cargo elevator fight. In the following the 4 common examples are shown:

The execution of the Raven fight on PC is entirely centered around using the godmode exploit (GME).
The more prevalent strategy that has been established is to begin the fight with the Socom. For this tutorial section
we look at the easy and extreme difficulty positions as example. For Normal and Hard difficulty Raven will be
in different spots. See those in the specific Raven Boss guide page linked under this segment.
Begin the Raven encounter by holding our Socom and pressing the the weapon and crouch key to begin to run and gun immediately.
with Snake and move left. During your run to the left, execute GME with pressing 0 for the PSG-1
and another weapon key (like 9 for chaff for example or 1 to return to the Socom) and turn the corner
to face Raven to the north. Send of your first shot and keep running at Raven until you are right in front of him.
Equip the Nikita and while standing in front of Raven, hold the Weapon button down. Once the Nikita LED
has blinked twice, enough time has passed to shoot Raven again since his i-frames have worn off.
If you run out of Nikita or intentionally didn't grab all the Nikita ammo when grabbing the weapon itself,
just behind Raven to his left is another Nikita ammo box with more shots.
This method is for Rank 1 strats incl. Big Boss on Extreme difficulty
Wait at least 61 seconds before leaving the room. Alternative listen in for the audio cue in the music, when the choir goes down for the third low note change, THEN leave when the strings start playing over the low note.
Wait 61 seconds at minimum again. The Audio cue with the fixed game OST plays the drum fill, then has the strings play a note that clearly is at odds with the rest of the music. A high pitch. Do NOT go into the small room with the pipes and steam, merely entering the Blast Furnace door counts for heating the pal key. The room transition can randomly delay the Pal Key change. See here different versions of grabbing the extra stinger ammo you need for extreme difficulty. On lower difficulty it can save frames not grabbing the warehouse north Stinger ammo, but the BF ammo.
ONLY FOR VERY EASY Save 2 seconds by area reloading After the warm key has been inserted and Liquid called you on the codec. Then call Otacon and wait outside the room. This way the door never closed but the flag for Otacon opening the door for you advances still.
