Fortnite: What to Know | PEOPLE.com

From obsessed teens to adult gamers, the game Fortnite is captivating players of all ages.

Since its release date on July 25, the free-to-play “Battle Royale” survival game has spread like wildfire across the eGaming industry.

The game’s online player count has reached over 125 million in under one year alone, Epic Games — Fortnite‘s parent company — said in a June release. Originally intended for computers and gaming consoles like the Xbox or PlayStation, the gaming giant made an iPhone version available for download on April 1 of this year, raking in over $25 million in its first month, according to Apple Insider.

Less than two months after the iPhone version came out, it became the top-selling app in the United States, the United Kingdom, and 11 other countries, according to PC Games News, outpacing even Netflix, Tinder, and YouTube.

The game has demolished several records, most notably for the amount of simultaneous online plays, with Rolling Stone reporting that over 3.4 million concurrents have logged on at the same time.

So what’s the deal with this viral action game? PEOPLE explains.

What’s the game all about?

Fortnite is essentially a survivalist game. The premise? Zombies have eviscerated 98 percent of the world population, and the player’s job is to roam around the natural grounds, build a shelter (hence the “fort” in Fortnite), gather supplies, and devise strategies to fend off the apocalypse. The platform allows users to get as creative as possible, from building a simple log cabin to a gargantuan, flame-throwing castle, and collecting other outfitted weapons. And — the best part for many — the game is designed to be played with friends.
