Rob Fahey of Eurogamer writes: Metal Gear Online is, Metal Gear Solid stripped down to its bare essentials, shorn of its characters, its cut-scenes and its cinematic ambitions. Divested of the storytelling elements that have provoked so much love and so much hate from gamers, Metal Gear Online instead offers up stealth and combat in their purest form - no cut-scenes, no missions, just 16 players waging online battles. Admittedly, this isn't the first time that Metal Gear Solid has sported an online component. MGS3's second incarnation, Subsistence, and the PSP's first proper MGS title, Portable Ops, both allowed players to take the game online, and both implemented it pretty well. However, neither console is noted for its online play, and it's fair to argue that Metal Gear Online on the PS3 represents the first really high-profile effort to bring the series online.
Whether Metal Gear Online can succeed at being seen as anything other than the online mode of MGS4 remains to be seen - but the promise of ongoing downloadable content releases and perhaps even full online distribution for the game is very promising, assuming Konami can get the price point right. Either way, we had a huge amount of fun with an afternoon spent playing Metal Gear Online - which, after being spoiled by the likes of Halo 3 and Call of Duty 4's magnificent online modes in recent months, strikes us as extremely promising. Whatever they think of Kojima's storytelling, every fan of online shooters should be keeping a close eye on MGO.
