Apex Legends is a free-to-play battle royale game developed by Respawn Entertainment and published by Electronic Arts. It was released for Microsoft Windows, PlayStation 4, and Xbox One on February 4, 2019, without any prior announcement or marketing. This game is FREE and can be downloaded using Origin on PC.
The game-play of Apex Legends is the most similar to Fortnite and Players Unknown: Battlegrounds, in the sense that both are battle royals. Where these games start to move away from Apex Legends can be summarized bellow.
Apex Legends has 9 different playable characters with there own abilities. They each have a Passive ability which works throughout the entire game and cannot be toggled manually. They all each have a specific Q and R ability. The Q ability is a champions main ability. It normally has a relatively lowish cool down and provides each champion with either a damage source or a healing source or just an all around helpful ability to get around the map. The ultimate ability is default on Z or R depending on your keyboard and computer. This ability is a champions most helpful tool. It can range from a portable trampoline which if jumped on shoots your allies and you far into the sky, helping you travel distances, All the way to a helicopter dropped missile strike that rains down in a straight line across a medium sized area. While the ultimate can be extremely helpful for getting you into/out of a fight, the cool down for these abilities is traditionally long... BUT the creators knew this and decided to add an item called a "Ultimate Accelerant" which if toggled takes 6-8 seconds to use and removes ~20% of your ultimates remaining cool down!
