Forsaken is a 1998 shooter video game developed by Probe Entertainment and published by Acclaim Entertainment. It was released for Microsoft Windows and PlayStation, with a port to the Nintendo 64 developed by Iguana UK releasing the same year as Forsaken 64.

A high-definition remaster developed by Nightdive Studios was released in 2018 for Microsoft Windows, macOS, Linux and Xbox One. The Nintendo 64 version was released on the Nintendo Classics service via the Mature 17+ app in 2025.

Forsaken is a 3D shooter in the style of Descent (1995), featuring similar weapons, power-ups, having missiles and mines being labeled "secondary weapons", and involving 3D movement of a vehicle through several tunnels. It is set on a futuristic Earth that, in 2113, had all of its life destroyed as a result of a shockwave from a science accident. The goal of the game differs between formats. In the PC and PlayStation versions, the player acts as someone trying to obtain the planet's lost treasure, while in the Nintendo 64 release, the goal is to kill looters finding the treasure. There are also elements of Quake.

The single-player mode has four difficulty modes: easy, normal, hard and total mayhem. Each has progressively stronger enemies and less ammo to spare. Due to the near-impossible challenge presented by the four modes, Acclaim provided the patch 1.00 that (among other things) decreased the difficulty of the game dramatically. There are 22 missions, each requiring the player to either destroy all enemy ships in a maze of tunnels, or achieve a certain target, such as completing within a time limit and/or at a specific percentage of enemies murdered. Similar to Starfox 64 (1997), different paths appear depending on which targets were achieved.

There are six different types of multiplayer games: Free for All (deathmatch), Team Game, Capture the Flag, Flag Chase, Bounty Hunt, and Team Bounty Hunt. There are various sub-options for each. Up to 16 players can join in on the PC version, four on the Nintendo 64, and two for the PlayStation. Also on the Nintendo 64 version, a maximum of three computer players can join. The PC version also has the ability to record demos.

The game was developed by Probe Entertainment during the 1996–1998 period as the company became merged into its parent company (Acclaim). At that time, Microsoft's newly bought and re-branded rendering layer (DirectX) had just started to dominate PC development.

Fergus McGovern headed the development team. The game was heavily technology driven at the beginning and was titled ProjectX.^{[citation needed]} This was changed to Condemned when the story elements were added although it was later changed to Forsaken due to a potential naming conflict.^{[clarification needed]}

A Sega Saturn version of the game was announced, but canceled as part of Acclaim's general withdrawal of support for the system.
