X-Com against many Alien races; Anthropods, Aquatoids & Sectoids - the whole concept from Apocalypse, Terror from the Deep & UFO:Defense.
In fact, three different mods in one including three extra Major Races; Interceptors(from X-Com), Thunderbirds(Yup, 1-2-3-4-5 Go!) and S-H-A-D-O (from the 80's TeeVee show known as UFO:Invasion).

This version updates the following;
- Introductory set of ships & fleets
- Tech Tree finalized
- Enhanced espionage assets
- Ultimate colonization & Extremes terraforming query tiles
- Plenty more!
