Fortnite

Fortnite is a co-op sandbox survival game developed by 'Epic Games' and 'People Can Fly' and published by Epic Games. The game was released as a paid-for early access title for Microsoft Windows, Mac OS, PlayStation 4 and Xbox One on July 25, 2017, with a full free-to-play release expected in 2018. The retail versions of the game were published by Gearbox Publishing, while online distribution of the PC versions is handled by Epic's launcher.

Save The World
The "Save the World" mode is described as a co-op sandbox survival game and is about exploration, scavenging items, crafting weapons, building fortified structures, and fighting waves of encroaching monsters. Tim Sweeney, Epic's founder, described the game as "Minecraft meets Left 4 Dead". The game plays in a third-person perspective and cycles between managing one's resources at a safe home base, and then going out on missions to complete quests as to collect resources and obtain rewards to advance the game's story.

In the meta-game, the player has an inventory of weapon and trap schematics, hero characters, defender characters, and support characters, along with collected resources. Schematics are used to construct weapons and traps when on the field. Hero characters represent characters from one of four classes that the player can use while on a mission, as well as used to undertake resource-gathering missions making them unavailable to use until they return from the mission. Defender characters can be summoned to help with defense but only if there are less than four players on a mission. Support characters are used to form various non-playable squads that provide passive bonuses to the player's attack strength, building speed, armor, and health, with additional benefits if the player can match certain characterization attributes within a squad. The player can spend different types of experience points and resources earned as mission rewards, from loot boxes (represented as llama pinatas), or other sources to level up and evolve schematics and characters. For weapons and traps, this generally boosts their effectiveness as well as unlocking additional attribute bonuses, while leveling up hero characters will unlock special skills the character has while in the field. Schematics and characters are generally assigned a rarity, which determines how much they can be leveled and evolved. A player's inventory of schematics and characters is limited, but players can opt to slot anyone they do not need into a collection book to gain rewards when certain collection sets are completed; use one or more of these schematics or characters to transform them into a new random item, or simply retire them to gain back experience points and other resources to free up the inventory slots.

The player also can spend skill points, earned by completing missions, and technology points, earned over time, to unlock new skills and technologies in the game's skill and technologies trees. These can improve a player's base attributes, attributes that are shared with the other players while on missions, unlock higher levels of evolution for schematics and characters, open up new squad positions, or unlock general skills that players can use in the field. Collectively, the player's progress on these skill and technology trees, their squad composition, and their selected hero character make up the player's current "power level" which relates to what difficulty of missions the player should take and the game's matchmaking services. Also, players can review their current story progress and quests, which can include daily, side, and event quests, which when completed provide in-game currency or resources.

Mission is currently divided between four world locations, some available only after progressing far enough in the story, and special locations for timed events and for the Survive the Storm mode. Within a location are several possible mission areas that show the type of mission, the terrain it takes place on, its difficulty rating relative to the player's current power level, and whether the mission is currently under special "storm" conditions that throw random effects, like buffed husks or mini-bosses, into the mission but have potentially better rewards if completed. The player optionally can select a special site that automatically matches them with players at a similar power level and story progression on a random mission for added rewards.

Most missions take place on procedurally-generated landscapes. Most missions are based on locating site(s) representing the objectives on the map, build up fortifications around those locations, and then face off against several waves of husks that will try to destroy the objectives. During completion of these missions, players are generally given a "storm forecast" to know where husks will spawn in as to enhance fortification in that direction, though this direction can change in more difficult missions. Other missions are time-limited, requiring the players to locate and help a number of survivors, build out several radar towers, or clear out various encampment of husks scattered around the map before time runs out. These missions encourage the players to explore the map and farm for resources (either by searching objects or destroying them with an axe) used to build the fortifications, weapons, ammunition, and traps needed to defend or attack the husks. Players also frequently need to seek out bluglo, a special resource that does not carry over between maps to activate certain mission objectives. Some missions are considered a loss if the objective is destroyed or time runs out, while other missions allow the players to rework their fortifications and start their defense again if the objective is destroyed. Maps will frequently have optional objectives that are discovered through exploration, such as human survivors that need help. Completing these successfully earn immediate in-game rewards such as resources, weapons, and traps. Missions themselves may provide bonus objectives, such as by completing the mission within a certain in-game period, using a limited number of fortification pieces, or saving more survivors than the minimum necessary, which affects the qualify of rewards the players receive after the successful completion of the main mission.

During missions, players can make their fortifications from one of three base materials (wood, brick, and metal), and in a number of configurations, including floors/ceilings, walls, stairs, and ramps; players have the ability to edit these for more configurations, such as adding a door or window to a wall. Each fortification part can be upgraded with more resources of the same type to improve their durability, and when they are damaged, can be repaired by spending additional resources. Traps, which have a limited number of activation before they fall apart, can be placed on floors, walls, and ceilings, and arranged in means to make them more lethal or effective against husks. Traps may also include beneficial resources for players, such as healing pads, defender posts, and launch pads. Similarly, players can use a range of weapons but these have limited durability that drops as they are used or as a penalty if the player should be downed by husks and need to respawn without the help of allies. Players can construct new weapons, ammo, and traps from gathered resources, or find these from searching containers across the map. During missions, the game progresses through an accelerated day-night cycle; during the day, the husks are more passive and do not generally pose immediate threats, while during the night, bands of husks may spawn in and will aggressively seek out players.

One unique mission type is Storm Shield Defense missions. In each of the four world locations, the player is allocated a map that remains persistent, representing the site where their base's storm shield generator is placed, and in the storm mode, the player must return to this map to expand the storm shield, requiring them to add a new objective to defend successfully to continue the story. At any time, the player can enter this map without starting the defense mission, and use their carried-over resources to build out the fortification and traps, or add resources to a special storage area for this map.

Fortnite is also able to offer themed-events with a unique progression line, new locations, and rewards based on those themes. The first such event was its Halloween event, "Fortnitemares", that offered Halloween-themed heroes, characters, weapons, and traps (usable outside of the event) by completing numerous objectives.

Battle Royale
The main gameplay for Fortnite: Battle Royale follows the battle royale genre's standard format: up to 100 players skydive then deploy a glider from the floating bus, known as the 'Battle Bus' onto a consistent map, which includes random distribution of weapons, shield, and other combat support features. The goal is to be the last player (or team, if playing in duos / squads) alive by killing or avoiding other players. Over time, the game's safe zone (representing the eye of a storm that is ravaging the world), decreases in size, and players caught outside the zone will take damage, potentially dying. This directs the surviving players into tighter spaces, forcing player encounters. Players can loot defeated enemies for equipment. Random supply drops will occur during a match, providing random weapons and items. Like in the original Fortnite game, Fortnite Battle Royale plays in a third-person perspective.

Fortnite Battle Royale's primary distinction from other battle royale games is the building system. Nearly all objects in the environment can be broken down into materials (wood, stone, and metal), which can then be used to build fortifications of limited durability, such as walls, ramps, floors, and roofs. These objects may be used to help traverse the map, protect the player from gunfire, or slow down progression of other players.

The game is free-to-play, supported by microtransactions that allow players to buy "V-Bucks", the game's internal currency. V-Bucks are also shared with the main Fortnite "Save the World" game, which offers players the opportunity to earn V-Bucks by completing missions or daily quests.[1] V-Bucks can then be used to buy cosmetic improvements to the player (heroes, character and weapon skins, and emotes). V-Bucks can also be used to buy Battle Passes which accelerate the rate that a player increases their Tier within the game's "seasons" (each season lasting a few months). By raising their tier, they gain automatic rewards of cosmetic items typically around a theme. Players can still increase tiers without a Battle Pass, albeit at a slower rate.
