File Description

Welcome to Into Cerberon version 0.0.2, code-named "Copper". Into Cerberon aims to bring the classic gameplay of the original 6-degrees-of-freedom game, Descent, into the high-powered realm of Doom³.

What's new:

This release ups the ante on 0.0.1 by including a brand-new map (Spectre's "ic_mine"), a functional HUD, new sound effects and music, and tons of bugfixes. Multiplayer is but may suffer in high-lag situations due to incomplete code that we hope to rectify in 0.0.2. Doom 3 1.3 required (RoE not required). This release includes binaries for Windows, Mac, and Linux, and we've even tested that Linux<->Windows play works fine!

Refer to the readme file for instructions; for bug reports or additional help please check in the IC 0.0.2 release forums thread.

Thanks for playing Into Cerberon!

Into Cerberon: Descent into Doom³.
A total conversion mod for Doom³

**IMPORTANT**: If you are installing 0.0.2 over a 0.0.1 release, please ensure that the mod folder name is all-LOWERCASE. As in 'C:\Doom3\intocerberon', not 'C:\Doom3\Intocerberon'. This applies for Linux and Mac users as well! Failure to rename to all-lowercase could cause problems with multiplayer.

README for Version 0.0.2 'Copper', Released 2006/05/19

Fly around 3 distinct maps with functional 6DoF controls and shoot up walls and other players with lasers, the minigun, and missiles.

Pretty much anything else.

Play with Linux and Mac buddies, see your ammo and health counters, and more (see version.txt for a complete list)

As with 0.0.1, this is most definitely a 'playable test' release, and not at a level of a beta or even an alpha. There are few pickups (and they don't all work), there are only three weapons, there are no crazy death animations, shooting lava doesn't cause it to explode, the controls seize up when lag hits, the collision model is awkward, the list goes on...

However, the game *does* 'basically' work. You CAN fly around and shoot stuff, by yourself or on a multiplayer server. We decided to release 0.0.2 because we feel it's a real, tangible, and significant improvement over 0.0.1; our general strategy with IC will be to release as often as we feel we can - anytime we have several coherent, reasonably functional features ready to ship.

This release's 'coherent, reasonably functional features' are:
- 6DoF controls, including roll
- 'Pyro GX' ship model with simple black paint job
- Dual lasers firing from roughly the appropriate points on the ship model
- Concussion missiles firing from alternating left/right tubes.
- Minigun weapon
- Three maps: ic_mine, ic_whatever, and ic_pipeline.
- Basic Headlights

There are many bugs or issues in this release that we are already aware of. Before reporting a bug, please check the topic called '0.0.2 (Copper) Released!' in the Into Cerberon general discussion forum at


To install, simply extract this ZIP file into your Doom3 folder. A new folder called 'intocerberon' should be created with several pk4 and this readme.


To play the mod, fire up Doom3 normally and then select 'Into Cerberon 0.0.2 (Copper)' from the mods menu. When Doom3 restarts, be sure to set up your graphics, sound, and control options. Do NOT click on 'new game'; this will start the singleplayer campaign, which doesn't work. The in-game server browser works for finding other IC servers but the maplist currently doesn't show IC maps, only standard doom3 ones. To host an IC server, see 'HOSTING A SERVER', below.

A default configuration file has been included with standard WASD controls. Please note that the configuration menu has not been updated to incorporate the new IC controls. If you wish to use a different keymap, in order to play this mod properly, you will need to bind three new commands:

'_button5' for left roll
'_button6' for right roll
'_impulse41' for headlights toggle

To bind a coommand, pull down the console (press '~' in multiplayer) and type:
bind X '_button5'
where X is the key you wish to bind the control to.

The standard WASD movement keymap included uses:
bind q '_button5'
bind e '_button6'
bind f '_impulse41'

Three guns are included in 0.0.2. They are the basic lasers (weapon 1), the minigun (weapon 2), and concussion missiles (weapon 6). You will start play with all three guns and plenty of ammo for each. Only one weapon can be fired at once. There are ammo pickups for the weapons on ic_mine and ic_pipeline only.

Three maps have been included in this release; they are not present in the multiplayer menu. The maps are called 'ic_mine' (new for 0.0.2), 'ic_pipeline', 'ic_whatever'. To change to one of them, type 'map X' where X is the map you wish to switch to. The game will automatically cycle between these two maps when nextmap is called.

Be advised that this release retains a squareish 'bounding box' for the player, which means that if you are up against a wall, you may not be able to rotate. Back away from the wall to be able to turn.


The easiest way to host a server is to run a dedicated server via a shortcut. Create a shortcut like the following:

C:\Doom3\DOOM3DED.exe +set fs_game intocerberon +set si_pure 0 +si_map ic_mine +set maxplayers 5 +set si_maxplayers 5 +spawnserver

This will start a dedicated 5-player server on ic_mine. You can then fire up Doom 3 and type 'connect localhost' in the server browser to connect. Alternatively, you can start a 'listen' server with almost the same command:

C:\Doom3\DOOM3.exe +set fs_game intocerberon +set si_pure 0 +si_map ic_mine +set maxplayers 5 +set si_maxplayers 5 +spawnserver

These examples assume that you installed Doom 3 to 'C:\Doom3', of course.


The principle contributors to this release are, in no particular order:
David 'Spectre' Matera, modeller & mapper
Johan 'iceheart' Strom, lead artist
Ron 'Narfig' Elliott, sound effects and music
Brian 'NoMercy' H, artist & mapper
Tim 'HeXetic' Gokcen, programmer & team lead

The music at the main menu is 'Descent Into Doom' (C) 2006 by Ron Elliott.

'Mine' (ic_mine) was mapped by Spectre
'Pipeline' (ic_pipeline) was mapped by NoMercy
'Whatever' (ic_whatever) was mapped by iceheart

The Pyro GX was modelled by Spectre, unwrapped by iceheart, and painted by NoMercy

This mod incorporates the Bloom/Skyportal mod version 2.02 by Use_Less and SantaClaws. Shouts out to them for making Doom³ look awesome.

The 'Shield Orb' image used as part of the loading screen was created by Rake, rake AT
The 'Violent Days' skyportal image was created by Hipshot, hipshot AT

Thanks to the rest of the official IC Team Members, in no particular order:
Ola 'Lug00ber' Gundelsby, music
Chris 'Mojo' Paine, music
Lee David 'LDAsh' Ash, modelling
David 'W3bbo' Rees, various

Our main goal with IC 0.0.3 will be to clean up the movement and net code and to enhance the playability of the game by fixing sound and lighting issues. There may also be a new map or two. We are aiming for short release cycles, so keep an eye on the IC site for updates.
