Cheaters never prosper
Chocolate Doom mirrors the original closely, including the built-in cheat codes. These can be used at any time during play, simply by typing them on the keyboard. In most cases, you will see a message confirming that the cheat has been activated. The cheats below assume you’re using a QWERTY keyboard.
Cheats can work in multiplayer Deathmatches, depending on the settings made by the person setting up the game — it is possible to add the flag “– nocheats” to prevent others from having an unfair advantage.
All cheats are prefixed by “id”, the name of the original game’s developer.
A few select cheats in no particular order are:
IDCHOPPERS
Why shoot the spawn of Hell humanely when you can carve them up with a gardening implement? This cheat will equip you with the chainsaw. Press 1 to select it.
IDCLEV##:
Use this cheat code to warp to the episode or map of your choice — for example “idclev02” would take you to Map 2. This has the same effect as starting a new game, in that your health will return to 100% and any power-ups and/or weapons you picked up will be lost.
IDDQD
This cheat sets your health permanently to 100%. This ‘God Mode’ will make you immune to most forms of damage, though certain types of floors can still harm you. You can also be killed by ‘telefragging’ — where other players or creatures teleport onto a spot where you’re standing.
There are plenty more along these lines for the lazy, desperate or perhaps less skilled player. For a full list of cheats, see the Doom Wiki at http://doom.wikia.com/wiki/ Doom_cheat_codes.
