Fortnite

Fortnite is a third person shooter survival game where the player has to survive against up to 99 other players. The total player count for each battle royale is 100. The player can build forts through collecting materials such as metal, bricks, and wood, and collect weapons before fighting other players. The main game also has a mode called "Fortnite: Save The World", which is also available as a separate game. While Battle Royale is free, Save The World is a paid game. The game can be played on Nintendo Switch, Windows, PS4, PS5, Xbox, and Android. 
Game modes.
Battle Royale.
100 players compete to win. Sometimes there are computer-controlled enemies. Players compete with each other to fight to the death. Players start with 100 health and 0 shield. In the game's "Zero Build" mode, players can have an Overshield which provides 50 more shield and regenerates when the player is not taking damage. in addition to their health and shield, players can find shield items to consume for a max of 200 hit points (or 100 health/100 shields). Players lose health and shields if they get shot by weapons, if they fall from too high, or take slow damage in the storm. The storm approaches over the course of a game. If the player loses all their health, they will lose. In "Fortnite", you can find different kinds of weaponry, including guns, boogie bombs and special items. Weapons can be obtained throughout the game by grabbing them in the open, opening chests and supply drops, looting them off enemies and eliminated players and fishing from the water. The winner of the match is the one who is the last man standing.
At the beginning of the game, you can get to different locations by skydiving from a flying school bus titled the Battle Bus. The battle bus goes in a straight line over the map, but the path is not always the same.
Creative.
Creative mode allows the building of anything players can think of. Players can copy and paste different objects from the Battle Royale mode, and are able to visit the map as well. They can rotate and enlarge them to any way they want, and explore the community built maps from other people.
Save the World.
"Fortnite: Save the World" is the original version of the game, first released on July 27, 2017.
Players must cooperate with others to kill Husks and complete various missions. One to four players cooperate towards a single goal that they both need to achieve in order to survive, and to win the mission. There are 4 main named locations that you unlock by progressing through the campaign. The first of which is Stonewood, the weakest of the 4 areas. Next is the mid-level Plankerton, followed by the high Level Canny Valley, ending with the last location, and the hardest, Twine Peaks. There are multiple other locations as well, added with events. One such is Scurvy Shoals, a tropical themed area.
Competitive.
Competitive Fortnite is played in Arena and tournaments. There are different kinds of tournaments. There are tournaments that everyone can play (free tournaments). They usually do not have any cash rewards if everyone can play them. The cups everyone gets to compete in are usually skin cups, where top 100 in each region gets a skin before its released to the item shop. For example, Thanos had a skin cup. 
Then there are Contender cups. In Contender cups, you need to be in the Contender League in a gamemode called "Arena". In order to get in a higher league, you need to earn "hype" a.k.a. "arena points" you get points for getting kills, placements and wins. Here are the different divisions, and how many points you need to be in it. 
In contender league cups, you usually just get arena points for participating. When you reach 7,500 arena points, you get to "Champion", here you can play tournaments for real money. You can also try and qualify for top tier tournaments, like FNCS, in contenders league, you can still play skin cups, and other special cups.
Cosmetics.
"Fortnite Battle Royale" has cosmetics. Cosmetics are items/skins that do not give the player any advantages in the game like pickaxes, dances, emotes, skins, wraps and sprays. Cosmetic items can be bought by the use of V-Bucks, the in-game currency. They can also be earned by completing challenges for the "Battle Pass", which is done by playing the game.
