Remanence

In the remains of a world where technology has progressed to the level of seeming magical, players take the role of a survivor of the apocalypse who aims to rise against the robotic cult that has destroyed the world using nanomachines. Armed with only a sword and little remaining nanomachine power, players must master sword combat and seek revenge on the cybernetic overlord. In their path is an army of machines with a variety of attacks. Some war machines are fast and nimble while others are slow but hit hard. It is up to the player to figure out the best approach to dispatch their opponent.(Storyline via IGDB)
