GTA 5 Online, or just GTA Online, is an online version of the original GTA 5 single-player game. It’s an online multiplayer action-adventure game, where you can enter the world of GTA 5 with various other gamers and play with them. Like the single-player version, GTA Online is an open-world game that allows you to participate in Co-Op or competitive matches. Unlike the story version of GTA 5, where you get to control three pre-made characters, the game’s multiplayer version features a single fully-customizable silent character that serves as your avatar. You can customize your character’s appearance, acquire properties, go on missions, earn money, and participate in various events with other GTA Online users. GTA Online comes free with the GTA 5 original game. However, there are various additional purchases you can pay for, which customize your character’s appearance and allow you to buy weapons, vehicles, properties, etc. Ever since the game’s release, its online mode has retained high levels of popularity among gamers.
