Ultima Underworld: The Stygian Abyss - Gameplay [HD]

Ultima Underworld: The Stygian Abyss is a first-person rpg / dungeon crawler game with immersive sim elements made by Blue Sky Productions and published by Origin Systems. It was released in 1992.

Ultima Underworld has been cited as the first role-playing game to feature first-person action in a 2.5D environment. Its design combines simulation elements with concepts from earlier role-playing video games, including Wizardry and Dungeon Master, which led the game's designers to call it a "dungeon simulation". As such, the game is non-linear and allows for emergent gameplay.

The game is set in the fantasy world of the Ultima series. It takes place inside the Great Stygian Abyss: a large cave system that contains the remnants of a failed utopian civilization. The player assumes the role of the Avatar—the Ultima series's protagonist—and attempts to find and rescue a baron's kidnapped daughter.

The player uses a freely movable mouse cursor to interact with the game's world, and with the icon-based interface on the heads-up display (HUD). Each icon has a specific effect; for example, the player uses the Look icon to examine objects closely, while the Fight icon causes the player character to ready their weapon. The player's progression through the game is non-linear: areas may be explored, and puzzles and quests finished, in any order. An automatically filling map, to which the player may add notes, records what the player has seen above a minimum level of brightness. The player character may carry light sources to extend the line of sight in varying amounts. Exploratory actions include looking up and down, jumping, and swimming.

Combat occurs in real-time, and the player character may use both melee and ranged weapons. The player attacks by holding the cursor over the game screen and clicking, depressing the button longer to inflict greater damage. Some weapons allow for different types of attacks depending on where the cursor is held; for example, clicking near the bottom of the screen may result in a jab, while clicking in the middle produces a slash. Simulated dice rolls occur behind the scenes to determine weapon accuracy. Enemies sometimes try to escape when near death, and the game's stealth mechanics may occasionally be used to avoid combat altogether. The player may cast spells by selecting an appropriate combination of runestones. Like mantras, runestones must be found in the game world before use. There are over forty spells, some undocumented; their effects range from causing earthquakes to flight.

The developers intended Ultima Underworld to be a realistic and interactive "dungeon simulation", rather than a straightforward role-playing video game. For example, many objects in the game have no actual use, while a lit torch may be used on corn to create popcorn. Weapons deteriorate with use, and the player character must eat and rest; light sources burn out unless extinguished before sleeping. A physics system allows, among other things, for items to bounce when thrown against surfaces. The game contains non-player characters (NPCs) with whom the player may interact by selecting dialogue choices from a menu. Most NPCs have possessions, and are willing to trade them. The game was designed to give players "a palette of strategies" with which to approach situations, and its simulation systems allow for emergent gameplay.

Ultima Underworld was conceived in 1989 by Origin Systems employee Paul Neurath. He had just completed work on Space Rogue, a hybrid title that features sequences both of 2D tile-based role-playing and of 3D space flight simulation. According to Neurath, Space Rogue "took the first, tentative steps in exploring a blend of RPG and simulation elements, and this seemed to me a promising direction." He felt that the way it combined the elements was jarring, however, and believed that he could create a more immersive experience.
