Epic Games begins development on 'Fortnite: Save the World', a cooperative survival game where players build fortifications to defend against waves of monsters.

'Fortnite: Save the World' is released in early access. While it gains a dedicated following, it doesn't achieve widespread mainstream success.

Epic Games releases 'Fortnite Battle Royale', a free-to-play battle royale mode inspired by games like 'PlayerUnknown's Battlegrounds'. This mode quickly gains immense popularity.

'Fortnite Battle Royale' becomes a global phenomenon, attracting millions of players and generating billions of dollars in revenue. Epic Games continuously updates the game with new content, events, and collaborations, keeping the game fresh and engaging.
