Valve should have made Left 4 Dead 2 Scavenge mode like gears of war 2 horde mode that would have been awesome!.
If you loved the original L4D, then you'll flip over L4D2...it surpasses the original in every way, shape or form...even my least favorite campaign Swamp Fever is still superior to any original L4D campaign...the campaigns in the new game are insanely cool and a lot longer...Versus rocks and so does Scavenge Mode and Realism is tough... BTW, the guy playing in this demo is a total noob...then again he's playing on an XBox 360...why they play with a console for a pc review is beyond me...damn kids these days...lol
I got it for the PC and wow. If you liked LFD1 then you will absolutely LOVE LFD2!! played through 4/5 campaigns so far and holy crap...Some EPIC zombie hunting going on in the sequel lol. The graphics really got ramped up significantly. Weather effects on the campaign Hard Rain are just insane. A must buy for any FPS co-op fan. Havent even touched the vs yet...I'm sure that's just brilliant as well.
OMG looks fun :). The real question is what platform to get it for, 360 or PC...hmmmm. I know the Source engine isnt really a resource hog so I might consider the PC version.
