The game also features custom gamemodes and modding support. He considered modding support an essential part of the full release as, just as he had his start with mods, he wants to enable others to create variations on his game so that he could “find the next PlayerUnknown”. This was aided by a quiet release of custom server support to a number of influential streamers which subsequently made it into public release. In one case, “Zombie Mode”, all but four players pretend to be zombies, who may sometimes distinguish themselves by removing all clothing and are limited only to collecting melee weapons and consumable items, and must rush to attack the other four players, who are able to collect all gear and attempt to outrun and defeat the zombies.
Inspired by this mode, Greene announced plans to introduce an official zombie-based gameplay mode based on this into PUBG. Whereas most of the rest of the team continued to develop the core gameplay and maps, Greene is taking on the zombie mode as a near solo project, only using the assistance of the lead animator to help with the zombie animations. Greene sees PUBG as a platform, and would like to see more custom game types and mods developed by players for it. Greene identified that some mods that he also previously worked on from ARMA 3 may become part of the Battlegrounds platform. Greene also wants to incorporate streaming services like Twitch into the game that would enable features supporting Battlegrounds’ development as an esport, calling this an “ultimate end goal” for his development, but he wanted to let it progress naturally with players.
