Metal Gear Solid: Ground Zeroes' campaign can be breezed through in less than two hours.That's what GameInformer is reporting anyway (via Kotaku). It's latest issue contains a hands-on look at Kojima Productions upcoming prologue for Metal Gear Solid 5: The Phantom Limb, where it stated, "Judged just by the core story mission, Ground Zeroes is short. We completed it in just less than two hours."It's worth noting that this didn't include side-quests or console-exclusive content like thebody snatchers-based Raiden mission on Microsoft consoles or the "Deja Vu" mission with pixelated PSOne Snake on Sony platforms.We've seen this sort of bite-sized prelude before with Dead Rising 2: Case Zero, but that only cost (3.40 / 4.80 / $4.99), whereas Ground Zeroes is priced at 19.99 on PS3 and Xbox 360 while its PS4 and Xbox One brethren are 29.99. There will also be a retail release on PS3 and Xbox 360 for 29.99.Eurogamer has reached out to Konami to see if this playtime is aberrant and to get an estimate on how long it might take to do everything in Ground Zeroes. We'll update if we hear anything.Metal Gear Solid: Ground Zeroes is out in the UK on 20th March and in North America on 18th March.
