Spellcross

This turn-based C&C/X-Com hybrid puts you in command of an extensive array of
modern-day sounding troops, needing to play battle after battle against the
merciless hordes of fantastical creatures (orcs, elves, skeletons, etc.) in an
attempt to save the world. As the game progresses your selection of troops
increase and you, hopefully, gain rank and lead your troops into trickier and
trickier battles. Only you can save mankind!
