Text: The game supports both single-player and up to four player cooperative mode while being online; there is no local online multiplayer. The game's quest system is the same in both modes. Players gather in multiplayer servers supporting up to sixteen players, during which they can post quests to invite others to join, or join other existing quests as long as they have progressed far enough in the game's storyline. If there are only one or two hunters on a quest, each brings with them a Palico (an anthropomorphic sentient cat species) to assist them in combat; these Palico can be equipped with weapons and armor crafted in the same manner as the hunter themselves. If there are less than four players in a party, a party member can launch a red SOS flare, which other players, while in their instance of Astera, can opt to join to help out, creating a drop-in/drop-out system. The game also supports Squads, the equivalent of clans or guilds in typical massive multiplayer online games. The game allows players in different release regions to work together; the game will use a pre-determined set of common greetings and commands that are translated to the various languages so that players can effectively communicate with each other. However, players are limited to cooperating with those on the same platform, and will not feature cross-platform play. Players also need to register with their console's service (PlayStation Network or Xbox Live) to use multiplayer features. With an aim to reach a wider audience than past games, Monster Hunter: World also provides more information to players, such as a companion that will warn the player when they are running low on health, and more details on the advantages and disadvantages of weapons and armors against specific monsters.
