Razer wants to tackle another part of the gaming experience -- namely, the drinks you need to keep your momentum going. It's introducing Respawn (no connection to that Respawn), a "mental performance" drink mix that's meant to keep your focus sharp for long periods. No, it's not a direct knock-off of its most conspicuous rival, G Fuel. You'll find a few familiar ingredients like choline and Vitamin B, and it's equally sugar-free, but there's none of the taurine and less caffeine (95mg versus 150mg). The Razer-owned brand doesn't want to risk the crash you get with energy drinks -- this is meant for those hours-long sessions where you don't want to slip.
