PUBG (Player Unknown's Battlegrounds) is a hugely successful and popular online shooter game. It's of so-called "battle royale" type - the game ends when the last team stays alive on a map. The difference to the normal deathmatch is that after you are killed in battle royale game you're not re-spawned anymore (perma-death). Here is the official game site. At the moment this competition was launched there were only two maps: "Erangel" and "Miramar". Currently, there is "Vikendi" as well but it is not included in our dataset.
