MCS: Mars City Security
-==May 2013 Update==-
Credits to the amazing Doom3 Community members that make MCS possible
In this update we would like to showcase the latest version of our MCS coop dev-build and talk a bit about the roadmap for summer 2013...
Further adjustments to the weapon-mechanics have been implemented allowing ironsights-aiming for weapons.
As mentioned in earlier news the goal now is to improve the way client prediction is handled making the whole coop clientside gaming experience less vulnerable to sub-optimal network conditions.
Fortunately the Doom3 BFG GPL sourcecode has been released in the meanwhile by id software providing us with the required netcode changes and so we used the past months to gather funds in order to be able to hire programmers with the required experience to backport those netcode changes from Doom3 BFG to Doom3 1.3.1.
Since MCS will be released as a free Doom3 download modproject all collected funds are used in a strictly non-profit manner with the goal to make a public coop beta available for download as soon as possible. In case you are a fan of MCS and would like to contribute in speeding up the public coop beta release process, you can now support the team by donating funds (5,00 $) at our MCS Donation Page.
Things are shaping up nicely and we are getting more excited each day as we make leaps towards a release date...
-==January 2013 Update==-
Here we have an early and raw port of rideable/controllable demons for MCS. As usual getting this to work across the network will be a real treat
All credits for the code go to the "FFteam" (Ivan_the_B, Starfir3, Neurological) and their Fragging Free project.
-==November 2012 Update==-
a tiny video update on a feature we are currently still testing. The idea was sparked by the
Doom 3 REVISED! Mod by OliveD and found its way into an MCS testbuild. The ironsights and
change of spread values definitely give the gameplay a more tactical touch.
Weapons and hand models are still subject to change in case we decide to implement these
new mechanics into the final MCS release candidate...
Now with the DOOM3 BFG GPL Source released the goal of implementing a new, more latency resistent netcode has come a lot closer. The BFG netcode was extensively tested clientside
and looks very very promising. Currently we are evaluating the amount of work required to
backport the BFG netcode to DOOM3 1.3.1.

I would like to take the time and update you guys on the progress MCS has made throughout the last couple of months and also go into details about which hurdles still need to be taken before we can finally start to think about public beta testing.
The goal with MCS from day one besides adding coop capabilities and updating it to current/next gen visuals, is to deliver clientside an as close as possible Listen Server experience. It became apparent that the stock Doom3 1.3.1 netcode isn't really the best foundation to achieve that goal (especially when clientside latency comes into play), so over the past months/years I first needed to identify the problem before I could think about ways of attacking it.
It turned out that Doom3 is using "forward prediction" trying to recreate the server's gamestate as accurate as possible at client-game-time which leads to a set of problems as soon as client latency (the delay a client has to the server) comes into play.
Basically what this means is that the game client tries to predict what game entities are doing BEFORE it actually gets the confirmed snapshots from the server. In a typical MCS scenario where a lot of dynamic events are happening this naturally leads to misprediction so that when the server snapshots arrive these errors are being instantly corrected.
We experience these corrections as "snapping" where on our client, another player or AI that happens to have been mispredicted is being snapped back to it's verified position/location/action according to the snapshots arriving from the server, making the entire gameplay feel quite jerky and sluggish clientside.
Although we are in the unique position with Doom3 to have the full SDK and GPL engine sourcecode available, a change from the current D3 client prediction model "extrapolation" to something more stable during higher client latencies ("interpolation") just recently became available with the release of the D3 BFG GPL sourcecode.
Backporting those D3 BFG client prediction changes require an experienced game programmer to analyse and rewrite the D3 1.3.1. code wherever needed. So a big amount of my time during the last months, I have spent searching for capable people willing to do those necessary steps in order to bring MCS closer to a public beta release.
Content-wise MCS is being updated frequently with features on the to-do list while others are being constantly added to the list during the developing progress.
Also I would like to apologize for the somewhat delayed updates here on moddb on my side but please keep in mind that this is basically a one man project and every side task, even the posting of news here on moddb is taking developing time away from MCS, so thanks for reading and tracking this project and stay tuned for more.
Todays media update consists of the new DemonWars map "Dalen" added to MCS with fully dynamic time of day capability co-developed by AphexJH.

Thanks to Simulation|EMZ's relentless technical support this month we successfully implemented a fully multiplayer compatible time of day system for the MCS gametype "DemonWars". The Global Sunlight, Ambientlight, Fog and Skybox now dynamically change and influence each other as the players cooperatively fight monsters over the network/internet.

The second video features 3 minutes of cooperative gameplay showcasing some of the latest game changes on the new time of day enabled Omega Complex DemonWars Arena map.
-==September 2011 Gameplay Walkthrough==-
The September 2011 MCS Build is showcased in this twelve minutes "Gameplay Walkthrough" video demonstrating the latest additions to the codebase. This video was recorded at 1080p clientside connected to a dedicated server. The showcased MCS group consists of two human players (the wife & me) and one friendly MCS AI player cooperatively fighting our way through a custom community made Doom3 map. One of the most important yet to implement features will be the a change of Doom3's netcode from currently "forward predicted" to "running behind the server" method. As soon as the Doom3 Source Code will be released later this year, that change, along with an improved projectile code, will ensure that clientside latency will become a much less influentual factor of the player's multiplayer cooperative gameplay experience. In order to speed up this process and thereby move faster towards a public build release, we welcome every interested & experienced c++ game programmer to join us in achieving the targeted goals.
Interested people can drop us a mail at email@example.com and we will be happy to provide you with all the tools and codebases required to get you started...
-==May 2011 Progress==-
Amoung many other SP Campaign related updates the gametype "DemonWars" was added to MCS which offers a more action/combat focused way to play the game outside the SP Campaign fighting against the Legions of Hell on Earth being humanity's last line of defense.
