Synopsis

Descent 3 is a first-person shooter in which players pilot a small ship with full six degrees of freedom through mines, cities and alien facilities. As a mercenary betrayed by a mining corporation, the pilot battles robots infected by a computer virus across a story-driven campaign. The Steam release includes the Mercenary expansion along with multiplayer for up to 16 players.

Reception

Critics in 1999 rated it highly, praising the varied levels with outdoor areas, the smart robot AI, the guidebot and the sound design. A few warned that the free flight could confuse newcomers or cause motion sickness, and some found the puzzle sections frustrating. For years the Steam version earned poor reviews because it crashed or refused to start on modern Windows. Since the source code release, players report that the community Piccu Engine makes it run smoothly with modern resolutions and fixed mouse handling.

3/5

Controls feel awkward on a modern controller or mouse and keyboard
Players report mouse problems with the original executable that only the Piccu Engine source port removes, and controllers can be remapped but lack full controller support. Source: pcgamingwiki.com, steamcommunity.com.
Menus, text or interface are hard to read on today's screens
The original game offers few resolutions, caps the frame rate at 50 by default and needs command line switches for widescreen, and resolutions above 2048 pixels crash it. Source: pcgamingwiki.com, steamcommunity.com.
Saving is fair: free saves or frequent checkpoints, little lost progress
Single-player games are kept as save files in the savegame folder; how freely saving works inside a level is not documented in the sources. Source: pcgamingwiki.com.
It teaches itself: no guide needed to make progress
The guidebot rides along, takes orders and leads the player toward each objective, and critics found it rarely got in the way. Source: icculus.org, gamerevolution.com.
Pacing holds up: little grind, filler or forced backtracking
Each level brings a fresh setting or hazard, such as dodging trains in a subway or darting between shadows on a sunlit surface, and clearer layouts than earlier games make the levels easier to navigate, with only a few frustrating puzzle sections. Source: icculus.org, steamcommunity.com.
Camera or movement fights the player
Full six degrees of freedom in tight tunnels leaves no fixed up direction, and critics warned that the flight can disorient newcomers and cause motion sickness. Source: metacritic.com, gamerevolution.com.
