I wonder how people do this

If you don't understand something about this walkthrough you can seek clarification here:

This isn't a walkthrough, it's just a rank run lol.

- In my opinion, walkthrough need to be smooth, flawless, fast, interesting to watch, well versed on tactics
- I build the toughest handicaps/challenges around NO DAMAGE accomplishment
- Your 400 hours of gameplay doesn't prove anything, I've met people who have several thousand hours of gameplay in some games and their skills are still average
- Your handgun run sounds impressive, but only sounds, because at the moment when you died the first time everything have lost its meaning
- And I'm still not sure that you even understand how hard it is to beat the game without damage on PRO/Fresh Start/No upgrades/S-Rank
- I suggest... try it... and you will see how difficult and special this can be
- Everyone has a right to their own opinion, and I also have the right to defend my work from absurd statements

- Your opinion is very shallow cause you form a judgement about my work after you only
saw a title of my run (and this is not the only example of your superficial opinion)
- And because of those kinds of things I feel offended when someone underestimate my work in a superficial way
- What you're talking about what you were doing in your run - it means nothing to me, blah, blah, blah...
- The main thing is to survive the game, not just to cross the game
- I don't see the point and the challenge in constant dying when you pass some hard obstacle from God knows how many attempts
- Take any player, and with so many deaths and constant repetition, every single player will somehow finish the game
- Some player will need more time and some will need less

Statistic was a variable that depended on level area difficulty.
Yes, enemies raped me but not in "every corner" only on some really hard areas.
Well you beat the game in "no damage" I beat game in "read from 4th line".
Chill dude, I'm not proving here anything just stating my opinion.
I don't have any videos, nor keeping in touch with my previous partner, nor I care so much to prove something here... Again just stating my opinion.
And about the last sentence which made me laugh a little (since I pumped +400 hours in this game myself)... What good is your run most the time (of course that not all the time) would be for run "don't pick additional weapons, don't buy anything and don't upgrade anything"? Because in my run it was: your gunpower is very weak, you almost always low bullets, you don't have other fancy weapons (GL, machine gun, sniper and etc?) and the latter means completely different tactics used?

Great... Steam limitations... Ok I'll post in 2 posts.
I feel a little tension from your answer... Don't be so touchy. Nothing personal but I said what I said.
I can repeat that this walkthrough from my point of view is "nothing special".
I'll reply in order:
Yes, I beat game on PRO + default pistol only + no upgrades + knife + no shop or additional ammo or any other items from other games (only exception are guns which available in boss areas like miniguns and flamethrower and grenades were used in whole campaign if we're talking about "only default pistol"). Only loot from enemies and what was found along the way was used to replenish ammo supplies, grenades and health items. Yes... Fresh start also...
Yes strategies we're used where it was possible.
Yes I died a lot (that what challenge is). On 3-4 (cannot remmember) very hard game areas I died 10-20 times (not mentioning my partner's deaths).

You wanna tell me that you beat the game on PRO/no upgrades ONLY WITH DEFAULT HANDGUN? My and my partner's gameplay is strategic walkthrough started FROM SCRATCH aka FRESH START (do you know what that means, huh?)... and where every move has sense and logic. And you know what...? We beat the game with NO DAMAGE. I am sure that in your "handgun run" your gameplay were a mess and enemies raped you around every corner (you took a lot of damage and deaths with bad statistic). Come back when you make videos that proves you can beat all those challenging handicaps I put in my walkthrough - and ONLY with M92F handgun. Until then be good and watch my videos you will maybe learn something.

Nothing special.
Try no upgrades + professional + basic pistol only (doubt you'll get a lot of S ranks but at least it would be some challenge...). Did that 1-2 years ago and some parts of the game were really challenging (especially chapter 2-2 boss 'cause there is a possibility that you run out of ammo if u not carreful and that means restart from 1-1).

Oh, I was actually expecting you guys to get the topas-marquise
