Riot Games has just rolled out one of its biggest patches ever for its highly popular League of Legends online battle arena title, in the form of update 4.20, which kicks off the so-called 2015 preseason period with a huge array of changes to the regular gameplay.

League of Legends is one of the most popular free-to-play titles in the multiplayer online battle arena (MOBA) genre, delivering a stellar experience to tens of millions of people from around the world.

The studio behind the title, Riot Games, has worked hard on keeping the experience as fun and fluid as possible, while leaving the door open for different innovations and enhancements, not to mention new champions for players to control.

Patch 4.20 is now available in LoL

Seeing as how the year is almost over, the studio is kicking off the special preseason period for 2015 and is rolling out a fresh update that takes the game to version 4.20 and brings forth a huge amount of changes to its actual gameplay.

According to the studio, the main theme of the upcoming period in League of Legends is strategic diversity, meaning players can have a greater impact in a match not only through their choice of champions but also through the strategy they use during the actual encounter.

"The big theme of the 2015 preseason is Strategic Diversity. That sounds like a vague concept, but our high-level philosophy is we want to offer you more paths to victory so that your in-game decisions matter just as much as the champions you pick," the studio explains on its website.

A huge amount of changes have been added

As a result, a huge amount of actual gameplay changes have been added that deal with the jungle area, the strategic items and modifications, not to mention the map-wide objectives and much more inside the popular MOBA experience.

"This year, rather than trying to 'fix' tactical problems from the previous season, we're instead introducing a metric ton of changes to map-wide objectives, a complete rehaul of the jungle and jungle itemization, and a number of strategic item additions / modifications. With these new paths in place, how you strive for victory will vary with each individual game and our hope is that all of this adds up to more far more strategic diversity and experimentation in League."
