Ultra-tech definitely. Also some Biotech is evident, if memory serves me correctly. They definitely have Psi in the game too, so Powers might be an additional requirement, though you might be able to do it with just the basic set.

Seems to me the TL might be TL9 or slightly above it for the human race. Weapons are still projectile-based. I played the game over a year ago, so I'm not sure what the specifics of power generation, transportation or medical would be TL-wise. I just remember I loved to hop out of the APC on a ridge and plug stuff from miles away with the sniper rifle (extra xp, yay!).
