X-com Series

[Demon of Light]

I know of no mods for this game but I remember that when I had TFTD, I used to go into the files for my aquanauts and do interesting things. My favorite was a creation named Bubba. His mind control abilities were off the charts but he had HUGE penalties to morale. Everytime someone died, he'd flip out and run smack into a tentaculat(sp).

You wouldn't happen to know how I could get Terror from the Deep, would you? I lost the program about two computers ago.

i know of no mods either, although I did at some point spend a bit of time looking around for old fansites.
As far as I can remember, the only things available were file editors, but you don't really need them - you can manually edit your savegames for money and soldiers stats, and make them pretty invincible - even though the game will be kinda boring from there on... but it may be fun to have a super sniper or a marathon runner or whatever else strikes you as interesting...

Edit: DL, I can't give you a link for it (I've already done that in another post, but Froggy edited it out), but do a search on google for ufo and underdogs, and you'll probably find it (it may not be the first hit, but likely the 2nd or 3rd result).
