Corsair announced the Nightsword v2 Wireless SD on June 4, 2026. The new mouse adds a dedicated Stream Deck button that triggers macros, app controls, and live‑stream commands without needing a separate device.
The button mirrors the functionality of Elgato’s Stream Deck, letting gamers and streamers fire pre‑set actions from the mouse itself. Corsair says the integration “brings the convenience of a Stream Deck to the palm of your hand,” streamlining workflow for content creators.
For owners of the original Nightsword, this is a modest upgrade that eliminates the need for a second peripheral. It may appeal to streamers looking to cut desk clutter, though the core gaming performance remains unchanged.
The Nightsword v2 Wireless SD arrives alongside Corsair’s existing mouse line, priced at $79.99, positioning it as a niche accessory rather than a must‑have for all gamers.
