The latest installment of the GemCraft series is a unique tower defense game, where, instead of towers, gems are the main weapon to fight endless hordes of monsters. Place your gems in towers, traps, or amplifiers, replace and switch them as you wish. Even combine them to create more powerful gems with powerful abilities, drop them as gem bombs or activate powerful buildings, the possibilities are endless, the choice is yours! Fight your way through an epic story, unfolding mysteries and facing sinister enemies and artifacts, as you try to entrap the Forgotten, an archdemon with an unknown agenda and no known way to kill, and to slay her demonic avatars, the shadows. Fierce and desperate battles await you...
