Command and Conquer (PC)

Command & Conquer is unarguably one of the most innovative real-time strategy games, introducing many features which are now commonplace in modern games of this genre. It was originally released for DOS, then later ported to the Windows 95 engine used by Red Alert as Command & Conquer Gold, which allows the game to be played at twice the resolution.

Unused Playback Demo
The DOS version has an undocumented parameter:. If the game is started with this parameter, it will start a playback demo after the game is kept idle on the title screen for one minute. This playback demo is very obviously unfinished, as it crashes after 45 seconds of gameplay. The demo is read off the otherwise unused RECORD.BIN file, stored inside the TRANSIT.MIX file, and by truncating this file, it is possible to have the demo finish. It's very likely that the developers simply ran out of time and were forced to ditch this feature.

The parameter was carried over to the Windows 95 version as well. However, it crashes right away as soon as it attempts to load the demo.

Special Options
There are 13 special options which can be enabled through CONQUER.INI, however the intended keys for these are unknown with the exception of the scores option since they are hashed in the executable.

Special Options Targeting flash visible to all. Allow targeting of trees. Allow undeploy of construction yard. Employ smarter self defense logic. Moderate production speed. Use three point turn logic. Tiberium will grow. Tiberium will spread. Disable building "bib" pieces. Allow running from immediate threats. Allow separate helipad purchase Tiberium grows quickly. Show true object names. Descriptions for some of the options can be found in conquer.eng, which is the game's string table. Note that there are descriptions for other options which aren't actually available as well.

The options can be forced on in C&C95.EXE by changing the bytes at the following offsets to.

TrueNames Options - 
 * Shows the actual names of civilian buildings in tooltips, rather than "Civilian Building."

Players Options - 
 * Allows six players in LAN games.

Rotation Options -  mNLeD_M6blU
 * Wheeled vehicles will make three-point turns, rather than turning on the spot like treaded vehicles. This is...interesting, to say the least.

Helipad Options - 
 * Helipads will be built without helicopters; their price will be adjusted from $1500 to $300 accordingly.

MCV Options - 
 * Selling a Construction Yard will undeploy it into a Mobile Construction Vehicle.

Bibs Options - 
 * Disables the "bib" of cleared land in front of structures.

TreeTarget Options - 
 * Makes trees valid targets. Normally trees have to be force-fired on.

Combat Options - 
 * It is not known what this option does.

Scores Options - 
 * Enables remixed variants of several music tracks, often with added vocals. This option can be enabled normally in the DOS version by adding the key Scores=remix under [Options] in CONQUER.INI, but will not work in v1.22 due to the removal of the option or the Windows 95 version due to the absence of the remixed music files.

CombatIQ Options - 
 * Enables "smarter" self-defense logic for units. Essentially, this makes units move any time they're shot at.

Overrun Options - 
 * Prevents Tiberium from spawning, meaning there will be none when starting a mission, and existing Tiberium won't spread or be seeded by blossom trees when loading a save game. Existing Tiberium patches will grow to maximum density as normal, however.

'''Sounds Options -
 * Enables alternate audio composed of human-vocalized versions of the sound effects.

'''Scrolling Options -
 * It is not known what this option does.

A utility to enable these options in any version of the game is available here.

Unused Music
Several music tracks are flagged to never appear in the Sound Controls menu's playlist. Two of the tracks are the credits themes; omitting them makes sense, but the following tracks are also omitted:

C&C 80's Mix (Covert Operations)



DIE!!



Enemies To Be Feared



Enemies To Be Feared (Remix)



Heartbreak



Reaching Out



Unused Sound
A short "popping" or "whooshing" sound effect is supposed to be played when a grenadier throws a grenade. The game tries to play toss, but the sound's filename is actually toss1.

Debug Mode
Another undocumented parameter,, was used by the developers to enable the game's debug modes. The only parameter still recognized by the game, however, is, which disables all sound and music output.
