League of Legends went through a dramatic transformation before launch. A YouTuber recently uncovered Riot Games' original investor pitch deck from when the MOBA carried the working title "Onslaught: War of the Immortals."
The pitch reveals a vastly different game. The core mode featured 6v6 team combat instead of the 5v5 that shipped in 2009. Champion designs differed wildly. Sion, who now appears as a towering undead warrior, originally sported a full beard and completely different aesthetics. The narrative framework centered on "an antichrist of sorts," suggesting a far darker, more mythologically grounded story than League's eventual lore direction.

Riot Games' pitch emphasized ambitious scope and player-versus-player combat during an era when Defense of the Ancients mods dominated PC gaming. The game's evolution from concept to launch shows how dramatically a title can shift during development, especially when facing competitive pressure and investor feedback.
League of Legends released in 2009 and became the world's most-played PC game for years. Riot's willingness to overhaul core mechanics and aesthetics during development positioned it to compete directly against established titles and ultimately capture the market. The 5v5 format became the competitive standard. Champion designs evolved into the detailed, character-driven roster players recognize today.
This historical document matters because it shows iteration at work. Modern live-service games rarely expose their pre-launch iterations. Most developers keep concept art and early design docs private. This leak reveals how even massive, successful franchises required radical pivots before finding their identity. The gap between "Onslaught: War of the Immortals" and League of Legends represents the distance between a
