The cult classic tower defense game beloved by millions comes to Steam with GemCraft - Chasing Shadows. Against swarms of vicious, demonic avatars, your only defenses are the gems you conjure that, when placed atop towers or into traps and amplifiers, become conduits for powerful magical and elemental attacks. GemCraft combines fast-paced real-time strategy as you deal with waves of incoming monsters, and cunning tactics that allow you to craft and combine magical gems.

Create traps that poison or slow, discover powerful artifacts and unlock new abilities, and stand alone against The Forgotten, a seemingly unkillable archdemon whose endless armies threaten to swallow the world. GemCraft is packed with multiple levels of difficulty, hundreds of achievements, nearly two hundred levels, and much, much more, making it a rewarding, deep strategy game you'll come back to over and over again.
