Warnings

SafeDisc retail DRM does not work on Windows Vista and later (see Availability for affected versions).

MechWarrior 3 is a singleplayer and multiplayer first-person and third-person action, FPS, TPS and vehicle combat game in the MechWarrior series.

The game received two official patches, as well as the Pirate's Moon expansion in December 1999, which introduced a new campaign, multiplayer maps and 'Mechs.

Since the Windows XP era, the game has had severe compatibility issues, which would manifest in one or more of the following: rendering and control issues, refusal to start up, broken physics and uncontrollable game speed. Two methods are known to resolve most of these issues on modern systems.

Issues fixed

Installing under modern Windows

For many people, the version of Installshield which MechWarrior 3 uses refuses to start, and instead just hangs. This appears to be caused by conflicting programs running in the background. Singling out which program this is can be quite difficult. A simple workaround is to create a new account with administrative privileges, and install MechWarrior 3 under that.[citation needed]

Alternatively, open task manager, go to details tab, right click setup.exe, click "analyse wait chain", tick both boxes to end both processes. Repeat these steps until setup launches.

Fix bouncing APCs and dysfunctional AMS

Limit the game's framerate to 30 FPS and/or force v-sync through a third-party application[citation needed]

Variable game speed

Game speed may constantly shift between too fast and too slow when the computer uptime is high.
Install the Widescreen Fix[3]

Pirate's Moon 4th pirate mission crashes often

Caused by corruption of data used by the game's physics code.
The game physics may still glitch out and destroy the player's mech, but the chances of completing the mission normally remain higher than on an unpatched game.
Instructions
  1. Download the unofficial patch.
  2. Copy file to <path-to-game>.
  3. Run the patched .exe.
  4. Try to complete the mission.
