Whether you are completely new to the game or came over from BR, there is a lot to pick up. I thought I'd do some helping alike by creating this short and basic FAQ for how to play Save The World.
1. FORTNITE began as Save the World months before BR was ever introduced later on. STW is a PVE and not a PVP. Your mission is to fight the Storm and its zombie-like monsters known as Husks. It's a building action and survival game where you build forts and stop the husks from breaking into your forts. You do things like rescue survivors, search for loot of all kinds and most importantly, building materials. Like in BR, the STW game environment is completely destructible. The only difference is the strategy. BR game tactics will most likely not work here if you're still thinking you are playing a PVP game; you are not.
2. FORT BUILDING in STW world is the same idea as in BR, but building forts like you do in BR does not always work and should be avoided. However, there is NO RULE(S) against building forts like you do in BR. Build whatever kind of fort you want. This is only a suggestion I am offering, not a mandatory rule.
TRAPS are essential for helping to defend your fort. There are ceiling, wall and floor traps. Now you can just build your fort without using traps and go ahead with repairing constantly when your fort is being attacked and damaged by husks. I'm just stating that traps will definitely give you a better chance at keeping the husks away from your fort. Now this is not 100% effective all the time; as there will be mistakes made when doing this and I have had my shares of many. Traps are a good idea when you are going solo in STW missions.
DEFENDER POSTS are a special type of trap that is a mat for summoning defenders you get when progressing along the game's main story quest line. They look like the typical survivors you rescue from missions. You have gunslingers, riflemen, snipers, shotgunners and bruisers (they use melee weapons). You get this trap as a schematic.
3. Schematics are plans where you can craft both weapons and traps for you to use. Crafting materials are needed to craft these items. Ammunition is also crafted in STW. Even though you can find ammo stashes throughout the game maps while on missions, crafting them is a good idea.
4. As a commander, you receive your HOME BASE and a storm shield. You get to name your storm/home base whatever you like. Now, your storm shield base is YOUR TURF. Build whatever you like to have it the way you want. But, you will have to focus on placing traps, defenses of sorts and such; due to upgrading your base's storm shield and husks will be attacking in waves. As you progress through the story's main quest line, you will know when you need to upgrade your storm shield.
YOUR COMMANDER'S POWER LEVEL determines if you are strong enough to enter what is called a "power level zone". These zones range from levels 1, 3, 5, etc. and get more dangerous as you progress. NOTE: If you see the description of a zone in RED, that means that you are TOO LOW a level to enter it; but the game cannot stop you from entering it. These powerful zones will only kill your character(s) faster if you choose to enter them when your power level is not equal to or greater than the zone's power level.
5. There are four areas that make up the STW world map. Stonewood (power 1 - 19) is first, then Plankerton (power 15 - 46), Canny Valley (power 40 - 70) being thrid, and finally Twine Peaks (power 70 - 128). As you progress from Stonewood onward, expect more powerful enemies, greater loot and definitely greater challenges. My suggestion to you is do not try to rush on through; trying to find the quickest way to progress through each world map area. TAKE YOUR TIME in your STW gaming. It's like I always have said: It does not matter how many great weapons you have that do umpty-number of damage per shot. If you don't have a game plan, don't know the mission and have NO CLUE as what to do/where you are going, you won't be progressing anywhere in STW at all. Once again, this is just suggestive advice I am offering; not a game rule written in stone.
6. There are four character/job class types to choose from known as heroes: Soldiers, Outlanders, Ninjas and Constructors. Each of these four types of character classes have their own strengths and weaknesses. Know each of their strengths and weaknesses alike. For knowing their weaknesses (in other words, what they are not capable of doing) and try to turn it to your advantage. For example: If the ninja character you are playing cannot do certain attacks that other ninjas can do, arm him/her with a weapon that will make up for that fact.
7. The most important rule of all to practice when playing Save the World is HAVE FUN! Please remember that THIS IS A GAME and not a contest to see who is better than who.
I hope that this brief guide will help new players to Save the World. Both BR and new players alike! Stay cool and continue to game the good games!
