Your hands are shaking, your mind is racing and it feels like your body is floating towards the ceiling.
Everyone knows that feeling when they've had too many energy drinks - and it's exactly that kind of sensation Sunset Overdrive attempts to recreate.
Based in the post-apocalyptic Sunset City, gamers are tasked with ridding the world of the OD'd, humans who have turned into grotesque marauding zombies after drinking a bad batch of Fizzco energy drinks.
Mostly, that involves explosive arcade fun mixing fast-paced action, sparkling cartoon graphics, gross-out humour and plenty of parkour with Tony Hawke's Skateboarding-style stunts.
That means there's a steep learning curve for beginners - give yourself a couple of hours to master the art of attacking the OD'd while ziplining and grinding your way around the city.
