Player versus environment in the context of Role-playing video game

A cooperative video game, often abbreviated as co-op video game, is a video game that allows players to work together as teammates, usually against one or more non-player character opponents (PvE). Co-op games can be played locally using one or multiple input controllers or over a network via local area networks, wide area networks, or the Internet.

Co-op gameplay has gained popularity as controller and networking technology has developed. On PCs, consoles and mobile devices, cooperative games have become increasingly common, and many genres of games—including shooter games, sports games, real-time strategy games, and massively multiplayer online games—include co-op modes.

Eve Online (stylised EVE Online) is a space-based, persistent-world massively-multiplayer online role-playing game (MMORPG) developed and published by CCP Games. Players of Eve Online can participate in a number of in-game professions and activities, including mining, piracy, manufacturing, trading, exploration, and combat (both player versus environment (PVE) and player versus player (PVP)). The game contains a total of 7,800 star systems that can be visited by players.

The game is renowned for its scale and complexity in regard to player interactions. In its single, shared game world, players engage in unscripted economic competition, warfare, and political schemes with other players. The Bloodbath of B-R5RB, a battle involving thousands of players in a single star system, took 21 hours and was recognized as one of the largest and most expensive battles in gaming history. Eve Online was exhibited at the Museum of Modern Art with a video including the historical events and accomplishments of the playerbase.

Player versus player (PvP) is a type of multiplayer interactive conflict within a game between human players. This is often compared to player versus environment (PvE), in which the game itself controls its players' opponents and is usually offline, whereas PvP tends to be online. The terms are most often used in games where both activities exist, particularly MMORPGs, MUDs, and other role-playing video games, to distinguish between game modes. PvP can be broadly used to describe any game, or aspect of a game, where players compete against each other. PvP is often controversial when used in role-playing games. In most cases, there are vast differences in abilities between players. PvP can even encourage experienced players to immediately attack and kill inexperienced players. PvP is often referred to as player killing in the cases of games which contain, but do not focus on, such interaction.
