Beating Metal Gear Solid 3 with no guns

This is a test run for a speedrun category extension I'm trying to create, commentary added post run. To my knowledge this has never been done before I could not find a run of this anywhere else. Adhering to my own rules this run is invalid but this is just to show that it is possible with the below rule set. Very fun run and very interesting routing hope other people give this a shot. After this is put up for review and if its accepted I will come back to it and beat it with whatever ruleset it ends up having.
MGS3 no guns rules im purposing
1. no guns
2. normal difficulty
3. no alerts
4. no continues
5. 1 kill
6. no boss camos
7. no special items
Rules expanded
1. no guns - you obviously have guns equipped after loads and cutscenes but as long as you are not actively using them (shooting, aiming, E-Z gun camo) you can hold them or even equip them in your menus for faster menuing later (Ex: Equip the M1911A1 in the GG Tunnel since it gets equipped after anyway).
2. normal difficulty - This is the hardest difficulty that this run can be accomplished on non-lethally mainly because of Ocelot (grenade cap goes from 20 to 5). Lethally it may be possible on Hard with nades and WP's but I'm not sure. Difficulties under Normal I believe would be trivial and too easy so it would not even be worth the challenge. Plus this gets more people to expierience Normal which I think is a very fun difficulty :)
3. no alerts/4. no continues/6. no boss camos - I believe this adds a much appreciated difficulty and routing method to this run rather than just rushing through everything with no regard for anything, again it would make the run too easy and trivial.
5. 1 kill - The kill belongs to Volgin 2/ Shagohod 2 it is impossible to non-lethally defeat him without the mk22 or the Mosin Nagant. If somebody can prove me wrong please do, this 1 kill is a stain on this run honestly.
7. no special items - runs with special items are dumb and bad lmao but with that said the infinite face paint is required if you would like to accomplish this on any other difficulty after Normal non-lethally and possibly lethally.
Done on PC Master Collection
