Doom II

Doom II: Hell on Earth, released September 30, 1994, is the sequel to Doom.

Story
The player once again takes the role of the Doomguy, who, after being killed on Phobos and subsequently fighting his way out of Deimos and Hell itself, returns home to Earth &mdash; only to find that it too has fallen victim to the hellish invasion.

The player progresses through 30 levels (not including two secret maps), attempting to free the remaining survivors of Earth's population, who are trapped in a spaceport and must escape via transporter. Once the Marine accomplishes this, he is free to live out the rest of his time alone on Earth while humanity hopefully continues on elsewhere. But along the way, he begins to learn how he might finally thwart the invasion once and for all...



Gameplay
Doom II is not a dramatically different game from its predecessor. There were no significant technological developments and no major graphical improvements; gameplay still consists of the player negotiating non-linear levels, picking up keys to unlock new areas, and of course shooting hundreds upon hundreds of monsters.

Unlike Doom, Doom II takes place over a single continuous sequence of linked levels, with brief textual interludes in order to advance the story. The intermission screens following each level show a simple background image instead of a map. The player can carry his weapons throughout the entire game (unless he is killed, of course), rather than starting from scratch several times as one episode ends and another begins.

The level design, as with Doom, is only loosely based on the areas the player travels through. As the plot begins on Earth, the early levels attempt a "real world" look, with some levels taking place in military installations and others in residential areas. Although some maps, such as MAP13: Downtown, do resemble terrestrial locations, most seem relatively abstract. Toward the end of the game, Hell has begun to merge with reality, and the final levels take place in a nightmarish, Dante-esque subterranean miasma of flowing lava and hot springs.

New enemies include the Chaingunner, Hell Knight, Mancubus, Revenant, Arachnotron, Pain Elemental, Arch-Vile, and a new boss, the Icon of Sin. The SS trooper from Wolfenstein 3D appears in the two secret levels, which are throwbacks in design (and music) to the Wolfenstein 3D game. Also, a Commander Keen figure makes a cameo in the second secret level.

The player's only new weapon is the Super shotgun. There is also one new powerup, the Megasphere.

In general, Doom II was well-received by the gaming community but was regarded in some areas as a disappointment. Its lack of major new features and its fairly homogeneous, sometimes drab level design were the biggest complaints. Nevertheless, Doom II went on to sell two million copies, making it the highest-selling id Software game to date. It also introduced the FPS multi-player world to MAP07: Dead Simple, which is regarded as one of the best deathmatch maps ever published.
