60-player matches via PlayStation Network immediately set Resistance 2 apart, not just from Killzone 2, but any shooter out there. The 32-player bouts in the original game were complete bloodbaths, so nearly doubling the player cap is only going to increase the chaos. Multiplayer in the first Resistance was often so out of control that you'd re-spawn only to get fragged seconds later. Fortunately, Insomniac is addressing this issue by encouraging squad-based tactics in these new 60-player matches.
New modes will undoubtedly make their way into the mix, joining popular ones like deathmatch and breach. Of course, if you'd rather avoid the huge competitive rounds there's always an 8-player cooperative mission. Resistance 2 will be the first game to ever feature it. Interestingly enough, Price describes online coop consisting of unique missions instead of simply remixing the single player campaign. All of this comes packed with a slew of online features including clans and experience points.
As for Killzone 2, little is known about what it will offer on the multiplayer side of the equation. Looking at what was available in the first game we can make an intelligent projection as to what the sequel will offer. PlayStation Network supports a wider range of features than previously possible so expect a larger maximum player count and expansive maps. Beyond this, we're in the dark as to what Killzone 2 will bring to the table.
Edge: Resistance 2
Resistance 2 handily takes this category. Without concrete details on what Killzone 2 will offer, it can't stay competitive in the face of a smorgasbord of features and 60-player matches. There's no question that the multiplayer in Resistance: Fall of Man surpassed the original Killzone – that alone gives Resistance 2 the edge.
