I have nothing exciting to report about Titanfall, Heart of the Swarm or Assassin's Creed Unity. I tested the mouse with Titanfall, StarCraft II: Heart of the Swarm, Assassin's Creed Unity and Star Wars: The Old Republic. While it doesn't present any significant problems for other genres, if you plunk down $130 for this mouse, you'd better be prepared to spend most of your time with World of Warcraft or a similar title. As the product's design suggests, the Naga Epic Chroma performs extremely well with MMOs.
