The slower pace might frustrate those used to COD4's adrenaline-soaked battles or Warhawk's arcadey clashes, but it's still a thrill. As a Metal Gear game it works beautifully, capturing the series' essence perfectly. [July 2008, p.108]
Although it has some regrettable issues, the execution of Metal Gear gameplay in an online setting makes for an enjoyable experience that is, at the very least, worth sinking a few hours into.
If, however, Konami plans to turn this into an ongoing spin-off with commercial potential then it needs serious work to either shape it into something outlandish that could only be done online with the Metal Gear series, or to better blend the Metal Gear elements into the established tropes of the multiplayer action genre.
