Diablo II PC System Requirements - Single Player
The game’s overall plot centers around the world of Sanctuary and the continuing struggle between the inhabits of the world with those of the underworld. Once again the Lord of Terror, as well as his hordes of minions and demons, are trying to return to Sanctuary and it is up to the players and an unnamed hero to once again defeat them. The game’s storyline is separated into four distinct acts, each of which follows a fairly linear path. Players progress through these acts by completing various quests that unlock new areas and allow players to gain experience and become more powerful for the challenges in the quests that follow. There are a number of side quests that are not required to move the main storyline along but they do allow players to pick up additional experience and treasure and gives some freedom of choice in the story. The game also contains three different difficulty levels, Normal, Nightmare, and Hell with the harder difficulty offering more rewards in terms of better items and more experience. This experience and items earned on harder difficulty settings are not lost if the player would return to the easier difficulty levels. On the flip side, monsters are much more difficult to defeat and players are penalized in terms of experience when dying on harder difficulty settings. In addition to the four-act single-player campaign, Diablo II includes a multiplayer component that was playable via LAN or Battle.net. Players could play with their character created in the single-player mode in the Open realms games which was one of the multiplayer modes. The game also supports co-operative gameplay with support for up to eight players in one game. One expansion pack has been released for Diablo II. Titled Lord of Destruction, it introduced two new character classes into the game, new items and added to the original storyline. It also overhauled of the game mechanics for both the single and multiplayer portions of the game. Diablo II was followed up by Diablo III in 2012.
