If you’re visiting this page, you most likely know the original game that Ufo: TTS is based upon. Therefore, the features listed here are only what will differ between both games. This list is by no means complete, as there are many more little details.

• Multiplayer – One person plays as humans, the other plays as Alien Invaders
• Singleplayer as either of sides. You can finally play as Ufo even in singleplayer mode
• Geoscape time passing in tactical combat – see day become night or the other way around.
• Rebalanced and reworked tactical combat. Its no longer as much luck based as it was. Its more about tactics, positions and using some of the previously not popular items (smoke screen for example will be more useful)
• Reworked air combat making it possible to engage 4 vs 4 crafts at a time. Also, air battle is now determined not only by range of weapons, but also by speed of the craft. Even if you equip long distance weapons, you cannot hold enemy crafts away for infinite time.
• Keyboard shortcuts
• Small, yet interesting changes to races, mostly to give them more combat flavour, instead of just ufopedia flavor. Remember reading Celatid’s description? Their flavor text mentioned they can detect human brain waves. Celatids in Ufo: TTS will also! Making them act like a radar for Muton soldiers.
• Alien ranks gain more meaning. Medic will finally be able to help his mates.
• Game works on XP and VISTA (of the tested systems. Might work on other windows familiy systems)
• many, many more…
