Heyyo,
Ok, tried this eclipse mod, was ok, nothing too amazing. It was rather short at just 3 levels though... An interesting idea for a mod, but the story diddn't quite unravel smoothly unless you actually read the manual.
If you've got a few minutes to burn, give it a go, otherwise you might be looking for a more entertaining 3rd person view game.
