Well, it's a computer game. Some people (particularly parents and government officials) seem to have trouble understanding this, but Carmageddon is, in fact, just a computer game. Honestly. I've double checked my research, and the 'computer game' theory of Carmageddon is accepted scientific fact.

No, of course not. While Carmageddon is pretty gory, and the main character is insane, it's just a game.
Playing Carmageddon doesn't make someone a demented maniac any more that playing Tomb Raider makes them a fat-chested archaeologist with a fetish for killing endangered animals.

The BBFC banned the original version of Carmageddon, so the zombies were put in instead. This decision has been overturned, and you can now buy the full-gore Max Pack in the UK. There are patches available restore the normal pedestrians, if you have the Zombie-version.

The German version has robots instead of people. (Due to government restrictions on violence)
Non-German versions of Carmageddon can be run in robot mode, if you like. To see Carmageddon with robots instead of pedestrians, use the -german switch. (Type "carma -german")

Either a joystick or the keypad is used to control your car, while the arrow keys change the camera postition.

You can only steal some cars, and you have to have a certain rank to steal a car. The rank depends on the car you are trying to steal.

Rank	Cars
89	Vlad, Ed-101, Mech
55	Screwie Lewie, Ivan
38	Psycho Pitbull, Otis
21	Don Dumpster
9	The Suppressor (Special forces APC)

You must waste an enemy car to have a chance at stealing it (You must get the credit. Don't let them fall in the ocean, or onto a mine)
It's quite random- just because you can steal a car doesn't mean you will. It's not uncommon to get halfway through the game before stealing you first car. Exception: You will always steal the Special Forces APC if you wreck it.
There is no other way to steal cars. There are no hints or tricks to make it happen. When you do steal a car, the text "Car added to change list" will flash on the screen.
Oh, and when you finish the game, you get access to ALL the cars. (You must complete the last 5 races and have rank 1 to win the game.)
Note: Many of the cars in the splat pack are also stealable, for example Stig's car, the doozer, the big rig, the monster truck, etc.

Dares (when another driver challenges you) do nothing but move you to the front of the start grid. They have absolutely no other effect.

Hiding on the level "Blood on the rooftops".
It's on the roof of a carpark building, up a spiral ramp, just past checkpoint 4. Be aware that sometimes it drives off the roof just before you get to it, so you may not always find it there.
Make sure you have max upgrades and a tough car before you take it on!

You need to do a full install. If you do, you will get the very cool CD audio. (Redbook Audio)
You can even play the Carmageddon CD music on an ordinary CD player (but DON'T play track 1- that's the game data)
If you have a full install but get no music, you might want to check the volume in your sound card's DOS mixer. Some cards default to near zero CD volume, and you'll have to increase it.

Carmageddon does not have midi music- the midi files and FM setup information was left on the CD from an older build.

There are 3Dfx patches for both the PC and Mac versions of the game.
No other 3D chipsets are supported by Carmageddon. There are no patches for cards like the rendition, powerVR, ViRGE, etc, and Carmageddon does not support OpenGL or Direct3D.

For the PC, I advise using the auto-installing 3Dfx patch. It has a file check to avoid attempting to install an incomplete download, a nice user interface, a FAQ, etc.
In order for the 3Dfx patch to work properly, you must have Glide installed and run the game in full DOS mode. If you are using a Voodoo 3 card, you may also have to remove the memory manager (EMM386.EXE) from your autoexec.bat file.

Wheels are supported. Set your device to analogue mode (if it's digital) and load any drivers it needs.
Run the game in DOS mode, and select joystick control. When calibrating, forward=accelerate, backward=brake and left and right mean turn the wheel. (so top left corner means accelerate and turn left.)
Joystick, wheel, and other input devices do not work in the demo.

You have to go into the key set-up screen and set the actions to movements on the joystick: select 'turn left' and then move your joystick left, etc.

Do a full install on all machines. The machine that is the host requires a CD, but the clients do not. (This means one CD can support up to 6 players.)
Make sure your network is functioning properly- You need to load network drivers in DOS mode, and they should be on the disk that came with your network card. Usually you run a file called IPX.COM, but some cards have a more complex setup.
The host (the fastest machine) should start a network game, while the others join a network game.
You will experience problems if you try to connect computers in DOS mode with those in Win95- run all machines in full DOS mode if possible. If not: Go into the Win95 network properties and select IPX properties, click 'advanced' then set Frame type to 802.3, Max Sockets to 32 and Max Connections to 16. This will allow games in the Win95 GUI to communicate with ones in full DOS mode. (Works on several other games, too...)

Carmageddon does NOT support internet play. IPX networks (Computers with network cards that are cabled to each other) is the only way to play Carmageddon multi-player. You must play over a local area network, not the internet.
Even if you use IPX emulation (kali, kahn, heat, zone, etc) it will not work properly. Carmageddon cannot handle the latency generated by phone line connections.

While it would be nice to play Carmageddon over the net, it just isn't going to happen. Carmageddon really cannot handle latency.

There are a lot of explanations for this, and a lot of enhancements that can be made to improve it (eg: prediction code, etc).
It doesn't alter the fact that because of the type of game it is, Carmageddon will always have problems over the net. Simply put:

1) Carmageddon is a fast paced game. The cars move a long way in a short time, so a comms spike would totally mess up the game. The characters in Quake, for example, don't move so quickly.
If you loose connection for 2000ms (Not exactly uncommon), a car you were chasing might warp half way across the map. You might get rammed and wasted by dumpy before you even knew he was there.

2) Exact position is vital. In quake/duke type games, most of the combat is at a distance, so with bullets flying about it's not vital that each character is in exactly the same position on each machine. That's not the case with Carmageddon. After a ram, the cars bounce off each other. If the cars are not in exactly the same position on each computer, they will wind up in totally different locations. The game will get badly out of sync. Prediction code is of less use since what happens is so dependant on exact positioning.

Nope, no modem play is included. If you have Win98, a high end computer and a clear line, you might be able to use Microsoft Dial Up Networking to simulate and IPX connection over the phone line and get a working game. However, modem to modem links have 150-300 ms latency, and that's often too much for Carmageddon to handle.

The cheats are very difficult to get working. Many people have had trouble. It takes quite a bit of practice to get them right.
Except where noted otherwise, they should be typed while playing the game (during a race).

You must type accurately, and don't hit any keys for a few seconds before or after the cheat.
Note the keys still have the normal function, and this can cause problems. For example [S]ound can cause a pause as the CD turns on, so you might 'loose' a keypress.
Your car should be stationary while you type a cheat. Getting hit by another car or moving seems to interrupt the cheat. (sometimes:)
When correctly done, the cheat will activate a few seconds after the last keypress. The cheats only work for the full version, not the beta or demo.

You might hear rumours of an 'enable' cheat- it was for the beta version, and not the full release.
The one thing you need to get the cheats to work is persistence. It will take a while to get the hang of it.

Additional Cheats:

Type in 'JOYRIDER' at the network race-type selection screen and you'll get access to all cars for network play. You'll need to select 'all' cars in the options screen to use them. This works with manual or random car selection.

On the race/car selection screen type :
KEVWOZEAR - This unlocks all races/all cars/all car upgrades
IWANTTOFIDDLE - Unencrypt all external text files. This is used to modify the weights/properties of objects and changing the physics of the game.

Type 'IBETYOUCANTPRINTCUNT' when in a race
F4 - Swap between ingame modes, mostly for track and car editing.

Bug- and one that should have been fixed before release. (Sorry Stainless, but it's not exactly hard to spot!)
If you have the UK version, you will have a file called patch.bat in the Carmageddon directory. Run this, and it should fix the problem (but only run it if you have trouble).

Well, the most powerful equipment (the 'cheat' equipment you can only buy after winning the game) will do this.
However, there is an intermittent bug that means you will occasionally get this power, even if you don't get those upgrades.
The solution is to change to the eagle, buy weak upgrades, race one complete track, then save. This usually seems to 'reset' it.

This is caused if you use a non-standard maths lib. While the custom ones may be faster, they are less accurate and can cause odd effects.

Hit [shift-D]. The screenshot will be placed in the DATA sub-directory, in BMP format.

Unfortunately, you can't do this without hacking the game.
The information is stored in the 'general.txt' file, and if you use the 'IWANTTOFIDDLE' cheat to decrypt the file, it can be altered. (be sure to back up your files before messing around, though.)

This is something that is unfortunately not possible in Carmageddon. You cannot have computer controlled AI cars or cops in multi-player games.

Each download should have some instructions in a readme file, but as a basic guide:
For cars-
'*.PIX' files should be put in the directory 'CARMA\DATA\PIXELMAP\'
'*.TXT' files should go to 'CARMA\DATA\CARS\'
For peds-
'*.TXT' files should be put in 'CARMA\DATA\'
'PROG.ACT' should go into the 'CARMA\DATA\ACTORS' folder
'*.WAV' files should be placed in the 'CARMA\DATA\SOUND' folder
