For starters, in Apex Legends, your only option is to play as part of a three-person squad. You can play in squads in Fortnite, PUBG and other battle royales, but they also have other game types to play with one friend or by yourself. There's a very good reason why there's only a single three-person squad gametype -- that's because of Apex Legends other main difference: It allows you to pick your class. And those classes are the first big difference between Apex Legends and its peers.

There are eight different "Legends" (character classes) to choose from in the game. Two of them are behind a paywall, so unless you pay $20 for enough of the game's premium currency: Apex Coins, your starting roster is comprised of six choices.
