Silent Threat is an official expansion pack for FreeSpace 1. Its major component is a new campaign documenting the Hades Rebellion, which introduces several new ships and weapons as well as new command briefings. It is also notable in that it includes dozens of fan-created missions. Silent Threat was released on the second of October, 1998.

Since the main Silent Threat campaign received relatively extensive criticism and is ostensibly somewhat weak—in both storyline and execution—,a fan-created extension of the main campaign was released: Silent Threat: Reborn. The campaign is an attempt to create a campaign without the shortcomings of the official one, namely plotholes and badly-scripted missions. This campaign is already available.
Much has been said about the campaign's defects. Yes, there is an Orion simply called "GTD" here (and it's furthermore referred to as a "cruiser"). Yes, there are no return to base directives anywhere, and all the targets are stationary and spew out an unlimited number of enemy fighters. Yes, there's not much dialog in the campaign, but there's something wonderful in the way the original ST is done: Playing on a sufficiently low difficulty level, there's nothing you need to worry about. ST requires no precognitive abilities to complete its missions, unlike its fan-made remade: There will be no EMP shockwaves that will render you incapacited because you did not jump out in a window of 5 seconds after killing everything. There will be no 15-minute-long missions that you will likely lose in the 14th minute. It's all about blowing up everything that gets in your way, sometimes while protecting something. These escort missions are just okay: there will be no single Zeus bomber that jumps in 8 kilometers away from you and, in 30 seconds, destroy the superpowerful space station you have been so ardently defending from an overwhelming enemy force. You will score a lot of kills in this campaign, and you may even single-handedly take on cruisers while your wingmen draw away hostile fighters' fire. Yes, the last mission is what it is: garbage, but then again, just play on a relaxing difficulty level, and you won't have a problem. - TopAce 16:15, 4 September 2009 (UTC)
