Corsair has launched the Nightsword v2 Wireless SD Stream Deck gaming mouse, a right-handed wireless mouse with a dedicated Stream Deck launch button, at Computex 2026.

The Stream Deck support is an in-house integration rather than a third-party collaboration, since Corsair owns Elgato. It brings Elgato’s shortcut system directly to the mouse, letting gamers, streamers, and creators trigger app, gaming, and workflow controls without reaching for a separate desktop panel.

Stream Deck controls are now under your thumb

The Nightsword v2 Wireless SD is detected inside the Stream Deck app. Once connected, users can assign Stream Deck actions to the mouse buttons and open Virtual Stream Deck menus through the dedicated Launch Button.

Once the mouse is set up in the Stream Deck app, users can assign shortcuts for Discord, microphone controls, audio levels, game launches, app switching, or multi-step actions. In games, those shortcuts could help with commands, emotes, or repeated actions. For streaming or work, they could reduce the clicks needed to mute a mic, open a tool, or move between commonly used apps.

The mouse also gets access to plugins and profiles through the Elgato Marketplace. That gives users more room to build app-specific controls, instead of relying only on standard button remapping.

The mouse still has serious gaming hardware

The Stream Deck button is the standout feature, but the Nightsword v2 Wireless SD is also built as a performance gaming mouse. It has a right-handed ergonomic shape, a sculpted thumb rest, 11 buttons, and three-zone RGB lighting. The mouse weighs 89g.

Corsair has used its Marksman S optical sensor, with DPI adjustment from 100 to 33,000 in 1-DPI increments. The main buttons use optical switches rated for up to 100 million clicks, and the mouse supports 8,000Hz polling.

Connectivity options include 2.4GHz wireless, Bluetooth 5.2 + LE, and wired USB. Battery life is rated at up to 170 hours over 2.4GHz with RGB off at 1,000Hz polling, or up to 47 hours at 8,000Hz polling. With lighting on, Corsair lists up to 42 hours at 1,000Hz and 25.5 hours at 8,000Hz. Bluetooth battery life is rated at up to 164 hours without backlighting.

The Nightsword v2 Wireless SD is priced at $129.99. It is currently available through the brand’s official website.

Call of Duty: Modern Warfare 4’s Stranded mission had me hooked for hours, yet left me wanting more

I spent hours sneaking through North Korea, scavenging supplies, and clearing outposts, and I’d happily do it all again.

Call of Duty: Modern Warfare 4 Stranded mission gameplay

For years, Call of Duty’s campaign mode has used big, scripted set pieces to tell the overarching story amid all the adrenaline-pumping action. The 2023 Modern Warfare 3 tried to shake up the established formula by introducing a handful of short open combat missions, and I genuinely liked the idea, but the game's overall negative reception seeped into how those missions were received.

I feared the next iteration might abandon the idea because of the backlash, but I am glad it didn't. MW4’s “Stranded” mission uses the same approach, but instead of fragmenting it across the campaign, it puts it all in a single large-scale open-world mission.

The $1300 Acer Predator Atlas 8 handheld is finally US-bound, and its pre-orders are already sold out

Acer’s first gaming handheld to launch in the US arrives November 1 with Intel Arc G3 Extreme hardware.

Intel Arc G3 Extreme Hands On with Acer Predator Atlas 8

Acer’s Predator Atlas 8 finally has a US release date and price, several months after the company first showed off the handheld in May. The highlight is the Intel Arc G3 Extreme chip inside, which has been adopted by only a couple of other consoles besides the Atlas 8. This version will go on sale exclusively at Best Buy on November 1 for $1,299.99.

Acer originally said the Atlas 8 would arrive in North America in October, but left pricing open at the time. The launch came amid the ongoing DRAM crunch, which has made memory more expensive across the PC industry and complicated pricing for hardware makers.

ASUS ROG Zephyrus G14 (2026) Review: Almost everything I want from a gaming laptop, except the price

Asus ROG Zephyrus G14 gaming laptop

Quick Take

Gaming laptops and I have a complicated relationship. One of my first gaming rigs was an Acer Predator that was already outdated when I bought it. I was a broke college kid, and that was the best I could afford. So trying out high-end gaming laptops is always fun. But ASUS' ROG Zephyrus G14 is a lot more than a laptop that can run AAA games. It is portable, so you're not lugging around a 2.5kg machine everywhere you go. It is built well, none of that plastic chassis, and can even function as a normal laptop outside of just gaming.
