PUBG Mobile’s Season 13 update introduced a number of notable new features. However, one of the most notable new additions that managed to fly under the radar was a new way the Kill vs Death ratio (K/D ratio) was implemented. The update changed the way K/D ratio is calculated for players.
Earlier, K/D ratio was calculated based on the total number of kills a player has by the total number of deaths. While this system seems to work on traditional multiplayer games, it was deemed unsuitable for PUG Mobile’s Battle Royale-style gameplay. The developers noted that players were boosting their K/D ratio by surviving till the end.
With Season 13, Tencent has introduced a new K/D system wherein the K/D ratio is calculated based on the number of kills a player gets in each game, regardless of whether the player survived till the end. This means that the new K/D ratio is calculated based on the total number of kills a player gets by the total games played by the player.
This means that if a player has a K/D ratio of eight according to PUBG Mobile's new calculation system, he/she will have to maintain a record of eight kills or more in every game in order to maintain and improve that kill record. Getting less kills in a game would reduce that K/D ratio.
The new K/D ratio is just one of the many subtle changes introduced in Season 13. Other subtle changes include firearm balancing (especially to shotguns), death replay improvement, new results screen UI and more. Of course, some of the major changes in the game include the addition of an upgraded version of the Miramar Map, canted sights, and more. You can learn more about the update here.
