ゲーム Doom II: Hell on Earth

In this sequel to the original Doom, you once again take on the role of the last space marine. Having been the hero who single-handedly saved Mars from demons, you return to Earth only to discover that the demons have already invaded, wiping out or possessing most of its inhabitants. Your task is to break down the force field around the last operational starport to allow the remnants of humanity to escape into space.

Doom II looks and plays very similarly to its predecessor, using the same 3D graphics with 2D sprites for enemies. The gameplay once more involves navigating the hero from a first-person perspective through 3D environments and shooting at demons while trying to find your way out by flipping switches and searching for keys. Unlike Doom, which is divided into three episodes, the 30 levels of Doom II (plus 2 secret levels) make up one long episode. Doom II adds one new weapon to the player's arsenal—the super shotgun—as well as several new types of demons with more advanced attacks compared to the first Doom, such as the chaingun-wielding Heavy Weapon Dudes, the skeletal Revenants who launch homing missiles, and the sinister Arch-Viles who have a highly damaging fire attack.
