This is the final section of my guide. I've decided to show you some of the more common equipment, including guns, armors and artifacts. I don't think that telling you about some rare pistols or machine guns would be a good thing, because you would probably have some serious problems finding these items. Even if you manage to do this, you won't have enough ammunition to use such a weapon for a longer period of time. As for the displayed objects, you shouldn't have any problems finding them in the game world. Additionally, it's been described in the walkthrough section of the game guide. This is when you will find a such an object for the first time. After that, you should be fine, because you will encounter these weapons and armors more often. I guess I should also tell you about the existence of a durability meter. This only includes the weapons, because armors and artifacts can't be worn down. If you're using a gun frequently, you will notice that durability bar has changed. You can't destroy a weapon entirely, however a gun with a lower durability rating is more likely to jam during a fight. As a result, you would have to spend at least a few seconds reloading it. Make sure that you change your main weapons every two maps, so you won't witness any problems.
MOST COMMON WEAPONS
PMm (280 RU)
This is one of the most primitive pistols. Sadly, you won't be allowed to choose anything more powerful at the start of the game. This weapon will only serve you to kill bandits and wild animals. You will have to remember about the poor accuracy and firepower. As a result, try aiming at the heads of your opponents, because otherwise you'll only slightly wound them.
Fort-15 (350 RU)
This is a slightly better gun and you'll be able to kill more creatures with it. It's very effective if you plan on exploring some of the first maps of the game. You could also use it to kill other Stalkers, however it can prove to be quite difficult. I wouldn't recommend using it against larger groups of enemy units. Nevertheless, consider using this weapon if you don't have enough ammo for the machine guns.
Sawn-off dbl-barrel (400 RU)
This is a very interesting weapon and it may come in handy early during the game, however you must remember about a few very important things. First of all, you will only be able to take two shots. After that, you must reload the weapon. It also takes a lot of time. Additionally, this gun is useful only indoors. Don't use it to kill enemies from larger distances, because you'll miss or you'll only wound them.
Akm 74/2U (1000 RU)
This is one the more interesting light machine guns. You won't have any problems finding ammunition for it. Other than that, this isn't a good weapon. You could use it early during the game, however don't expect to kill soldiers or animals without any major problems. Use it only if you don't have anything better in your inventory.
Viper 5 (1100 RU)
Viper 5 is one of the most common light machine guns. You will find a lot of these objects in Cordon and Garbage, mostly because bandits are using them. Sadly, you won't find this weapon to be useful, mostly because it's not powerful and the accuracy is very poor. The only advantage of having it is that you won't have any problems finding more ammunition.
Akm 74/2 (2000 RU)
The standard version of Akm 74/2 is much more interesting and you will probably use it in Garbage and Agroprom. Sadly, you will have some problems finding more ammunition, so don't use it against less powerful bandits or wild animals. Once you've acquired a Fast-shooting version, you may get rid of this weapon, because you won't need it anymore.
Fast-shooting Akm 74/2 (2000 RU)
You will probably come across this weapon for the first time ever while exploring Strelok's stash. I'd strongly recommend that you take it with you, because it's much more powerful than a standard version, especially if you prefer choosing longer bursts (instead of single shots). This weapon will allow you to take on several opponents at once, without having to worry about losing your life.
Chaser 13 (2150 RU)
An excellent shotgun. It's much more interesting than Sawn-off dbl-barrel, mostly because you won't have to reload it that often. This weapon is most effective while fighting indoors. It also takes down mutants very easily, allowing you to finish them off. You will find more powerful machine guns (even for smaller distances) later during the game, so you won't have to use this weapon anymore.
Obokan (2500 RU)
This is a slightly better weapon than the Fast-shooting Akm 74/2. Nevertheless, I wouldn't recommend exchanging it for that weapon, because you would have to be on a look out for a very rare ammunition type. You would also have do deal with smaller firepower while using longer bursts, instead of single shots. Leave a place in the inventory for something better...
IL 86 (4000 RU)
Interesting and quite useful machine gun. Obviously it's better than the Akm74/2. The problem is that you won't be able to gather enough ammunition in order to use it all the time. You could check local traders for additional supplies, however it's best to wait for the main character to find something better and more common in the game world. This weapon has a built-in scope, so you wouldn't have to search for it on your own.
TRs 301 (5000 RU)
A VERY useful gun and I'm sure that it's going to be one of your favourite ones. First of all, TRs 301 is much more powerful than the previous guns from this list. As a result, you will be killing enemy soldiers more efficiently. TRs 301 is also very accurate, so you may use it as a sniper rifle, however you would have to find a new scope for it (Susat Scope), because the standard one won't fit. Check the guide if you want to know where it is.
SGI 5k (6500 RU)
Some of the Freedom soldiers will be carrying this machine gun. Sadly, there's nothing good I could say about it. If you're already in Army Warehouses district, I'm almost certain that you'll be able to find something more powerful. Additionally, SGI 5k doesn't have a scope, so you wouldn't be able to use it to kill enemies from larger distances.
Tunder S14 (10000 RU)
Just as before, you will probably come across this weapon for the first time while trying to explore Army Warehouses. This is a standard weapon of all Duty soldier, so if you're fighting for Freedom, you shouldn't have any problems acquiring it. Tunder S14 is a powerful weapon, however I would recommend that you take the GP37 instead of this gun.
RPG-7u (10000 RU)
Rocket launcher looks cool and fires missiles, however you won't find it to be very useful. The only advantage is a high price, so you'll be able to sell it in Bar or Cordon. I wouldn't recommend carrying it in your inventory, because it would have only slown you down. I'm sure that you're going to take down all hostiles without having to use this weapon on them.
SVUmk2 (10000 RU)
This is one of the few available sniper rifles. I'm sure that you'll know exactly how to use it against distant enemies or monsters. Other than that, you won't find it to be very useful. Additionally, it's very hard to find more ammunition for this weapon, so it's best that you stick with the GP37 rifle, especially since the sniper rifle weighs a lot more and you would have to get rid of other objects in order to have it in your inventory.
Sniper rifle (SVDm 2) (15000 RU)
This is a much more powerful sniper rifle. You will be able to find this weapon in Red Forest (check sniper locations). I guess there's nothing more I could say about this weapon. You could take it with you, however you would have to deal with its weight. You would also have to be on a look out for a very rare ammunition type.
FT 200M (17000 RU)
This is a very interesting weapon, however you will probably find it near the end of the game. FT 200M offers huge firepower. This weapon is even deadlier than GP 37, especially while fighting indoors. It's also quite accurate. You shouldn't have any problems finding more ammunition for it. Most of the enemy soldiers will also be using it, so you will be able to exchange your current weapon for a model with a higher durability bar.
GP 37 (18000 RU)
This is by far the most useful weapon of the game, at least in my personal opinion. You will probably come across this gun for the first time ever while clearing out Freedom's base in Army Warehouses. The main advantages of having this weapon are: firepower (both single shots and longer bursts) and accuracy (it could replace your sniper rifle). Additionally, you won't have any problems finding more ammunition. Acquire this gun as soon as possible.
Gauss gun (25000 RU)
This is the most powerful weapon of the entire game. Sadly, you won't be able to find it earlier. Gauss Gun is a very unusual sniper weapon. You can only go for single shots and after you've fired the weapon, you will have to wait a few seconds for it to recharge. As a result, use it to take down single foes (you can't miss!). Don't even consider trying to kill larger groups of enemy soldiers. Thankfully, you won't have any problems finding more ammunition.
MOST COMMON ARMORS
Leather Jacket (1000 RU)
You will be using this armor at the start of the game. Obviously you shouldn't expect too much from the leather jacket, however it will do just fine while trying to explore Garbage or Cordon districts. Nevertheless, you should consider acquiring better artifacts, especially those which will allow you to extend your life meter. Stay away from anomalies since you won't be protected from their effects. Thankfully, you won't find too many of them early during the game. The same goes with radioactive zones.
Monolith suit (10000 RU)
You will probably come across this armor for the first time ever while going through some of the cabinets in the X18 laboratory. The Monolith Suit theoretically is weaker than the Stalker Suit, however I found it to be more useful. First of all, Monolith suit offers a much better protections from gunshot wounds. The only disadvantage of having is that you would have to pay more attention on avoiding the anomalies and chemical substances. Nevertheless, you should consider taking it, especially since you'll be taking part in a lot of difficult fights.
Stalker suit (15000 RU)
This is probably going to be your first armor, so you will be able to see the difference once you're wearing it and you're in a middle of a fight. Stalker suit offers better protection from all different types of threats, including gunshot wounds. You will be able to use a bulletproof vest in order to survive some of the tougher fights. Don't worry about the rest of the parameters, because you will find better armors later during the game.
Ghost suit (15000 RU)
You will be able to find this suit only in one specific location (Ghost's body in the final section of the X16 laboratory map), however I've decided to display it here, mostly because it's very interesting. Ghost Suit doesn't offer a better protection than the Monolith suit, however it allows you to regenerate your health without having to use medical supplies. If you wind this feature to be useful, you should consider exchanging it for the Monolith suit. Otherwise leave it with Ghost, because you'll find better armors anyway.
Ecologist suit (15000 RU)
This is an interesting proposition, however only if you're not taking part in a lot of difficult fights. You would have to avoid most of the enemy units, because this suit doesn't offer a proper protection against these types of attacks. Instead, you will be protected against different types of threats - chemical, electrical, fire... It also offers better protection from the radiation, so you'll be able to explore some of the well hidden stashes. You will be able to buy an upgraded version of this suit later during the game and I think that's exactly what you should consider doing.
SEVA suit (30000 RU)
This is without a doubt the best armor of the entire game. You will be able to purchase this suit from Professor Sakharov, however you will have to explore the X16 laboratory in the first place. I'm sure that you won't have any problems using this armor until the end. First of all, SEVA suit offers similar protection to the Ecologist suit, however it also has a much better bulletproof vest, so you won't have to avoid any fights. Just make sure that you have enough money in your possession in order to be able to buy it!
Exoskeleton (50000 RU)
You will find this armor near the end of the game. Despite what you might think, this is NOT the best armor you could possibly find, mostly because it doesn't offer a proper protection against radiation. You should also know that some of the final locations are highly radioactive... As for the main advantages of having it, exoskeleton offers best possible protection against standard enemy attacks.
