Gauss weapons - the TFTD equivalent of lasers - are utter dross. Even the bigger guns - the sonic cannons - will barely scratch the toughest aliens. The pistols in the first game would actually kill some aliens the equivalent in TFTD is only good for target practice. Otherwise - the aliens were generally tougher, and your weapons crappier. Researching corpses in the original game was entirely optional in TFTD, you need to research key corpses (and live aliens) to unlock certain technologies. (IE autopsy+artifact both required for one new technology) Many research topics require research in to two seemingly unrelated fields. Originally posted by drinsano:The Tech progression is also more complex in TFTD. Many many ambushes because of it costing soldiers or the compulsory door opening rookie. You cannot open doors without walking through them like you can in TFTD. UFO is actually harder due to one simple thing. Since actually they are mostly a retexture of each other with a few balance changes. This was fixed in TFTD so it stomped many many people.Ī third thing that plays into it and isnt related to the game itself is that many people played TFTD first and then went back to UFO no experienced in the game so they found it far less challenging than TFTD which they were just leanring.Īs a whole the games are very very similiar.

It wasn't noticed by many since the aliens got such a massive leg up to start with. There was a bug in UFO that meant after your first save it was set to the easiest difficulty. It has very little real impact except on the really high difficulties.Ģ. i.e Not all weapons work in all environments, the alien AI and stats is slightly improved,multi level missions and so on. There are some design choices that do make the game more difficult.
