Eclipse Mod is a mod for Space Empires IV which adds a whole lot to the standard tech tree, as well as a bunch of new graphics and sounds. Gas giants are truly huge in this mod - up to 640 times the size of a normal planet, though that will be reduced in v1.02 to offset gas giant native races' advantage of having such large homeworlds! Eclipse features some really wild techs such as teleportation devices that add combat movement to ships and even bases, psionic minesweepers, weapons which double as warp point closers, and more. It also has ships that are really easy to propel at high speeds, though that will be toned down in v1.02 as well. And of course, since this mod was designed by Kevin Arisa, it features his high-quality shipsets such as the Eneron, Borak, and Chillian.
