This week, Valve's Left 4 Dead makes its grand entrance, ready to delight us with hours of blasting apart leprous, brain-eating zombies. But don't overlook Need For Speed: Undercover on the same day. Mortal Kombat vs. DC Universe, also out today. Let's not forget Lips on the 360, although the only place I really sing is in the shower, and I don't think they've waterproofed the peripherals for that. The count for this week as we march onward to Black Friday: 26 titles on the Wii; 23 on the DS; 16 for the Xbox 360, 15 on the PC, 11 for PS3 and PS2; just two for PSP. The entire list is on the jump.Today Mortal Kombat vs. DC Universe (PS3, 360) Shaun White Snowboarding (DS, PS2, PS3, 360, PSP) Guitar Hero: On Tour Decades (DS) AC/DC Live: Rock Band Track Pack (Wii) Animal Crossing: City Folk (Wii) Shaun White Snowboarding: Road Trip (Wii) Monday (Nov. 17) Left 4 Dead (360) Need for Speed Undercover (DS, PC, PS2, PS3, PSP, Wii, 360) NCAA Basketball 09 (PS2, PS3, 360) Rock Band Track Pack Volume 2 (PS2, PS3, Wii, 360) Strong Bad's Cool Game for Attractive People Episode 4: Dangeresque 3: The Criminal Projective (PC, Wii) Tecmo Bowl: Kickoff (DS) Gallop and Ride (Wii) Hello Kitty: Big City Dreams (DS) Merv Griffin's Crosswords (Wii) Robocalypse (DS) Spore Creepy & Cute Parts Pack (PC) Target Toss Pro: Bags (Wii) The Lord of the Rings Online: Mines of Moria Complete Edition (PC) The Sims 2 Mansion & Garden Stuff (PC) Tuesday (Nov. 18) Castlevania Judgment (Wii) Left 4 Dead (PC) Lips (360) Tomb Raider Underworld (DS, PC, PS3, Wii, 360) Agatha Christie: Evil Under the Sun (Wii) Alone in the Dark: Inferno (PS3) AMF Bowling World Lanes (Wii) Bolt (DS, PC, PS2, PS3, Wii, 360) Championship Foosball (Wii) Cooking Mama World Kitchen (Wii) Cradle of Rome (DS) CSI: NY (PC) Dynasty Warriors 6 (PC, PS2) EverQuest II: The Shadow Odyssey (PC) Gothic 3 - Forsaken Gods (PC) Imagine; Movie Star (DS) Imagine: Ballet Star (DS) Iron Chef America: Supreme Cuisine (DS) Karaoke Revolution Presents: American Idol Encore 2 (PS3, Wii, 360) Legendary (PC) Luminous Arc 2 (DS) Metal Slug 7 (DS) Monkey Mischief: Party Time (Wii) Mortimer Beckett and the Secrets of Spooky Manor (Wii) Naruto: The Broken Bond (360) Neverwinter Nights 2: Storm of Zehir (PC) NPPL Championship Paintball 2009 (PS2, PS3, Wii, 360) Petz Catz Clan (DS) Petz Crazy Monkeyz (Wii) Petz Monkeyz House (DS) Petz Rescue Endangered Paradise (DS) Rayman Raving Rabbids TV Party (DS, Wii) Rune Factory 2: A Fantasy Harvest Moon (DS) Skate City Heroes (Wii) Ski & Shoot (PS2) Ski Doo: Snowmobile Challenge (PS3, 360) Sonic Unleashed (PS2, Wii) Tony Hawk's Motion/Hue Pixel Painter (DS) Ultimate Band (DS, Wii) Winter Sports 2: The Next Challenge (DS, PS2, 360) You're in the Movies (360) Wednesday (Nov. 19) Burnout Anthology (PS2) Skate It (DS, Wii) Thursday (Nov. 20) The Last Remnant (360) Friday (Nov. 21) Beyond Protocol (PC)
