The game neverwinter nights has many modules, ranging from DND - Sci-fi - to horror, thanks to its amazing tool-set and scripting capabilities. Though sometimes it takes a while to get setup due to having to download the many different addons (HAKS) Specific to each module, its worth it in the end. This module, is called X-COM Area 51 (Theres also a Prequel called X-INV, which I can also host as well for anyone interested) Both made by Mulu and Lazybones.
If you have the game never-winter nights (an all expansions) and like free-form role play then this is for you. The NWN adaption of the classic game X-COM , The first sightings were fairly benign though they included reports of abduction. Many rejoiced at the irrefutable evidence of extraterrestrial intelligence, while others claimed the world was going to end. Then the abductions increased....
The governments of the Earth are scrambling to come up with a defense to the alien menace. You have all been handpicked to be the first assault team for "X-COM": the Extraterrestrial Combat Unit.
You start in a secret base in Area 51. Your tasks are as follows:
1. Respond to alien attacks with deadly force.
2. Retrieve alien artifacts for scientific analysis.
3. If possible, capture aliens alive for interrogation and study.
The Area 51 base has a state of the art laboratory, as well as a workshop capable of manufacturing just about anything. Top scientists and engineers from around the globe have been retained to provide you with the resources necessary to be the front line in defending the earth. The experimental SkyRanger craft allows you to deploy rapidly and with great range.
Since this is a NWN adaption there are some major differences from the actual game - that being - there is no world map, consider it like a dynamic campaign, its laid out infront of you but there are more then one way to complete different missions. Can be played with multiple players or just 1, and with NPCs, if you are interested stop by the vault and start downloading,
