At the main menu, select "Options", then choose the "Keyboard/Mouse" selection. Enable the "Allow Developers Console" option. While playing the game, press ~ to display the console window. Type "Exec 360controller.cfg" and press [Enter], then set your split screen mode with the following console codes: "ss_splitmode 1" ("Horizontal-Cut" for standard monitors) or "ss_splitmode 2" ("Vertical-Cut" for widescreen monitors). Connect to a server. Join the server with the "connect [IP address] 2" console code. You must now set the Xbox 360 controller to player two (with the light on the Xbox logo pointing to "2"). To do this, quickly unplug and reinsert the Xbox 360 controller while the game is running. You can now play in Co-op mode in split-screen.

Invincibility while reloadingPress [Reload], then hold [Melee] to knock back attacking zombies while reloading your gun. -From: Ryan Helgeson

Fast meleeRapidly tap [Melee], [Weapon Switch] repeatedly. This will double your melee speed. This helps to complete the game on the Expert difficulty from hordes of attacking zombies.

Safe areaWhen hordes of Infected appear, try to find a room with a door and no windows. Go inside, and close the door. The Infected may break the door, but when you see a hole in it, shoot the Infected trying to break it down. Your teammates can handle most of the Infected.

Unbreakable doorIf you are low on health and need somewhere to hide, find a bathroom stall. Go inside the stall, and close the door. The door never breaks down. This works well if you are trying to heal yourself.

Easy wins as Infected in Blood Harvest: The TunnelThere is a warehouse-type area immediately after the starting safe room. Quickly run back to the emergency door on the other side of the warehouse. There should be a forklift near the door. Spawn and push this forklift in front of the doorway. Note: You may need to break the white door in front of the emergency door to get the forklift all the way in front of the doorway.

Shortcut in Dead Air: The Construction SiteThere is a metal door and a raised fence by the barricade that you burn. Jump on the fence, and follow it until it begins to go downward. At this point, jump on the metal siding door. Note: Some practice may be required.

Shortcut in Dead Air: The CraneJump on the fence after climbing on the vent cover. Go across the fence, then jump to the other side of the horizontal fence. Turn left, and go to the end. Jump up and to the right to the air conditioning unit box on the corner of the next building. Once on the next building, go to the left corner. Jump to the top branch of the tree below you. You will lose a lot of health after landing; however, you will be at the next safe room.
