Alongside the various weapons, you can find some special items and tools. Some of which can heal you, others are vital to completing an objective.
The Torch-It portable welding torch can both weld shut and cut open metal doors, gates, and more. It is a gun-like body with a removable and replaceable oxy-acetylene canister. It can be used as a melee weapon with a quick or charged attack. Alternate fire (hold down mouse2) will turn on the gas and pilot and burn through any lock, door or gate.
Sometimes you need to put out some fires to get to your next objective. In order to do that, you'll need a Fire Extinguisher. It can be used as a melee weapon with a quick or charged attack, or you can use it to put out fires by holding down your secondary fire key (mouse2).
Barricading's a staple in every zombie film and game, and it naturally makes an appearance here as well. In order to barricade, you need to find a hammer and some boards. Once you found both, equip the hammer and hit your secondary fire key (mouse2 by default) to enter "Barricading Mode". Once you found a doorway that can be barricaded (it'll have some semi-transparent boards on it), tap your primary fire key (mouse1 by default) to start barricading.
There are a series of items that one can use to temporarily cure infection, heal their wounds, or bandage their cuts. Some of them are listed below, but to use any of them you must pick them up with your USE key (E), and equip it through the Inventory Wheel. After you've done that, you can finally use them by tapping your Primary Fire key (left click).
Phalanx is a prescription drug developed in the in-game universe of No More Room in Hell by real-life pharmacutical giant Pfizer. It was intended to treat those infected with 732-ZH Encephalitis Lethargica. It was a commercial success but a clinical failure. The world collapsed before Pfizer could complete research in to an effective drug treatment, but players can find bottles of Phalanx scattered around in rare places in most maps and can use it to stem off infection in themselves or others for a short time.
When used, it will be immediately consumed and take effect. It lasts for approximately three minutes before it wears off and infection sets back in from the start.
You can only hold one of these at a time.
If you are in BLEEDING status (represented by an occasional pulsating splash of blood on your screen, along with a grunt of pain and a trail of blood coming out of your character), you can find these bandages to stop the bleeding. You can only hold one of these at a time. Once used, they'll also replenish 15 health points. Note: You can't use these bandages if you're not bleeding!
First Aid Kit
The First Aid Kit, or FAK, can replenish 40% of your health if used. You can only hold one at a time. It will stop the BLEEDING status.
If you have one of these in your inventory, you're able to listen to and communicate with other Walkie Talkie users, regardless of how far you are from them. These are used passively, so you can simply speak with Voice Chat. Some maps may also use them as a way to communicate objectives or important pieces of information to the player.
This is your flashlight. Unlike in other games, you won't start out with this, so you'll have to find one of these scattered throughout the level you're on. If you press F, you'll switch to the Maglite. Right clicking will turn on/off the light. Pressing F again will switch you back to the weapon you had previously equipped.
Some weapons will allow you to use them and a Maglite at the same time (pistols, some melee weapons, etc.). To do this, simply press F.
In addition to the above, you're able to see the full
flashlight beam emitted by other players; this means you can have one person shine a light through a pitch black hallway, and have the other survivors kill the now visible zombies!
On occasion you might find a flare gun. You can use these things as improvised weapons (they're great at setting zombies on fire), or you can use them to call for supply drops. To call for a supply drop (if the map allows it), simply aim at the sky and shoot.
If you're caught in the dark and you don't have a flashlight, you can tap F to bring out your Lighter and left click to light it. Keep in mind that you might have to left click several times before it works. If you sprint or keep the Zippo lit for 60 seconds, the flame goes out.
If you have a Maglite in your inventory, you can bring the Zippo out by holding down the F key for half a second.
Future updates will potentially give the Zippo Lighter more functionality.
