[Updated] Stack up bodies in Left 4 Dead 2’s Cold Stream for DLC!

Killing zombies is a tough task, Cold Stream in Left 4 Dead 2 actually makes that to new levels. Valve is trying to sweeten the deal as the add-on is slated for release, if they can get 20,000 people to survive the onslaught they’ll release Dead Air for L4D2 early on July 10th. Players can beat the campaign on any difficulty to earn the new achievement and help everyone enjoy the goods a little earlier.

Check out the official blog post for more information or jump on Steam and lend a hand. I’ll be in the fight in just a bit as well.

Update – Playthrough tips:

  • When you can grab a second pistol do so, you’ll have 30 rounds to unleash when your primary weapon goes out of ammo
  • Melee strike as much as possible when reloading, try to maintain the high ground and if you’re playing in SP, grab high range weapons like the sniper rifle to pick enemies off before leading the AI in.
  • The waves rely on users moving forward after the first attack, doing so leaves you open to being surrounded, fight the first flood and then wait for the second before going forward. If your team is tightly held you can last through these waves.
  • Solo players will die, you can’t rush in these maps, trying is pretty much suicide and leaves the team with one less person
  • On the bridge, beware of some glitches in crossing the beams, if someone falls there is a chance they’ll get stuck on the side railing until they die, trying to save them is pointless as they’ll instantly go into falling mode again.
  • In the final map have at least one person get the grenade launcher, save the rounds as much as possible, in the final zone unload the rounds to reduce the swarms to 0.
  • Heal your team often but always try to keep 1-2 med packs in reserve, in some cases the game will ask for a sacrifice, if you survive they’ll have a med pack waiting unless someone hijacks it and leaves you for dead. (Bridge scene has a charger that blows you off the scaffolding if you don’t have grenade rounds).

Xbox 360 users:The L4D team has confirmed that the 360 version of Cold Stream will arrive later this summer.

Completed using: Dual Handguns, Grenade Launcher, M249 SAW, Sniper Rifle (primary)

Hopefully these lend a hand in getting through Cold Stream and get you a new badge. Completed it in 49mins solo on hard, well designed but the boundary boxes need work still and the AI enemies and team often get stuck or make really odd mistakes through the entire campaign.
