Well, this is new. When a developer talks about length, they're typically referring to the single-player element.
And that's because the multiplayer has no story and hence, no beginning and no end. But many games allow you to rank up online and some fans say, "I wonder how long it'll take me to reach the top rank…" Well, in Crysis 2 , that process will take around 60 hours . And here's a progression video:
You can view a few of the upgrades seen in that video through the link above; there's cool stuff like Stealth Enhance and Tracker (highlight the footsteps of other players), and four separate armor modes were highlighted: Air Stomp, Threat Tracer, Detonation Delay, and Rapid Fire.
There's no doubt that Crysis 2 is a relatively deep shooter, and the online multiplayer component looks great. The only question left is whether or not Crytek can deliver on all their lofty claims…
