Open Falcon is an unauthorised community addon for the original Microprose Falcon 4 simulation. It is based on earlier Falcon 4:BMS code. The addon requires an original unpatched installation of Falcon 4 from the original Microprose CDROM. Open Falcon cannot be installed over Falcon 4: Allied Force. It is a standalone title and is not multiplayer compatible with the original Falcon 4, Falcon 4: Allied Force or any other community version of Falcon 4 including Free Falcon/RedViper or differing version of Open Falcon.


Version comparison

One reason you may choose Open Falcon over other Falcon versions, is that 3D pit MFD extraction is possible using Open Falcon and Lighting's MDF Extractor utility. This allows you to show the MFDs on another display while in the 3D cockpit. In Allied Force, Free Falcon and Red Viper only 2D pit MFD extraction is possible. Also for pit builders Aeyes has a special transparent 3D pit that only shows the HUD. Open Falcon has graphical enhancements over Allied Force while offering greater stability than Free Falcon 5.


  • Improved graphics including a clickable 3D cockpit, new flare and smoke effects
  • Improved avionics
  • Greater system complexity
  • Eurofighter Typhoon
  • Updated Tactical Reference screens with photographs
  • More functional panels for pitbuilders thread


The first release of Open Falcon was in controversial circumstances with the release of a unauthorised "beta" to a popular Bittorrent site. Prior to this release a small group had boasted to forums regarding their use of the addon but had not publicly released it. Following the unauthorised release the group established a website and forums at and released additional versions of the addon culminating in a "one click installer" version 4.5.

After the release of version 4.5 the developers indicated development was ceasing, released a last set of some of the fixes intended for the version 4.6 release and shutdown the website. However the forums subsequently reemerged on a new domain and version 4.7 was released in December 2008. The forums then moved to in May 2009.


Support for Open Falcon is available on the Global Falcon forums at (free forum registration required).
