HZM Coop Mod UPDATER tool is here!

We have now a new tool for you, it updates your Coop Mod to the latest version by a click of a button!

We are very proud to present this tool to you. You might notice that the tool has many additional features besides the updating. Some of these additional features are not yet complete, none the less the Updater is working great and will make your and our life much simpler when it comes to updating/maintaining the HZM Coop Mod.

HZM Coop Mod Updater Tool Screenshot

Here are a few things you should know about the updater.

  • The Tool runs on Windows 7,8 and 10
  • The Tool needs Microsoft .NET 4.0 Client (which is usually easy to get)
  • The Coop Mod Updater needs to be placed (Manual installation) inside the game directory, right next to the base folder, not inside of it!
  • The Coop Mod Updater needs to be started with administrative privileges or it will not work.
  • There is a Autoupdater that can also install the Coop Mod Updater Tool for you.
  • It can Forces to download the latest update, which is handy if there are any sort of issues
  • It can allow the installation of the Official patch 1.1, if there are issues from older mod installations.
  • It can Manage your CD-Key, alter, copy and create a backup.
  • It can Manage the Masterserver entry of your game its exe file.
  • It allows you to use a own coop mod update server, it can also create a php server side script for the your own updater server.

HZM Coop Mod Updater Updater Screenshot

The Autoupdater, it sounds funny to have a updater for a updater, but it all makes sense. Applications can not update them self while they are running, they need another program to replace their old version with the new one, and this is exactly what this little Autoupdater does ;).
Here is what you need to know about the Autoupdater:

  • The Autoupdater can install the HZM Coop Mod Updater Tool ONLY if your game is installed correctly (registry entries intact).
  • The Autoupdater needs to be started with administrative privileges.
  • The Autoupdater will automatically find your valid game installation and and work with it.
  • The Autoupdater allows you to select which shortcuts are to be created.

We recommend that you download and try the Autoupdater first, because if it works it will do all the configuration for you. If the Autoupdater fails due to missing registry entries you can try the HZM Coop Mod Updater tool. If that fails too, please contact HazardModding. Go to HELP -> ABOUT THIS PROGRAM

download now Autoupdater
Autoupdater for automatic installation (recommended since it is easier).

Windows Smart Screen Warning Dialog

That we have not yet managed to verify our Updater Tools according to Microsoft Guidelines, so there will be a Warning displayed from Windows that the Publisher of the Program could not be verified. Windows might refuse to start the program, you then have to click on more, configure or information inside that warning dialog to run the program anyway. We try to fix that issue as soon as possible, but we are new to .NET, so that may take a while.

Version 6.01 is here!

The latest version of our Star Trek Elite Force II Coop Mod is finally here, after a full year of hard work on the Version 6 of our Coop Mod it is virtually complete.

We want to share what makes this version so special to us...

  • Programmed in C++, almost no more limits
    This means a lot to us, since in C++ we are given a freedom to alter the game its native code with almost no limits. Adding new features and fixing many stock game bugs is now possible with ease.
  • Fully multiplayer compatible Tricorder Puzzles
    Tricorder Puzzles are now working exactly like they do in singleplayer, starting from the Modulation bar to the complex wave modulation all features work!
  • Fully compatible multiplayer Cinematics or CUTSCENES
    This is obviously a big deal, cinematic sequences are on default fully compatible to the Multiplayer, on any map. With the exception of the fakeplayer command all script commands will work perfect in Multiplayer.
  • Working multiplayer Radar
    This is a great help for the players, since it is marking the location of the current Mission Objective on the map. We also plan to expand this feature just a little bit more, so that we may come as close as possible to the actual Singleplayer Radar.
  • Levels Scripts made compatible to Coop in a matter of minutes
    Level scripts are now so extremely compatible most levels would even work perfectly without changing the scripts to suit it for coop.
    This is quite a game changer in terms of providing new levels for the coop mod. We have reprogrammed the Entire Coop Mod in C++ and all started to convert all Singleplayer level scripts from scratch, all this in one Year with only two man working on the Project, this shows how much the changes in C++ did take this Mod forward.
  • Level Scripts for Coop go into a separate folder
    This way we can prevent any Script Problems occurring in the regular Singleplayer. How ever, this does not grantee that there will be no issues created by the Coop mod.
  • Featuring the complete GBS Mod campaign
    Since it is now so very easy to make scripts coop compatible we have made the complete A Gate two Birds and the beautiful Sky" Mod available for Cooperative play.
  • Featuring Episode 1 of the ROTEC Mod campaign
    We have also integrated the first four levels from the "Return of the empty Crown" Mod, otherwise known as ROTEC Episode 1. We have not been able to reach the Author of this Mod. Even though that we assume the Author will not object to his work being used in the coop mod it can still happen that the Author instructs us to remove his files from our mod, so we are not sure if ROTEC will be there and expanded upon in the future.
  • Featuring the Coop Mod experimental maps
    We have also included the Coop Mod experimental and test maps for you to play cooperatively. They don't make for good missions, because they are designed to test, show and teach how levels can be made interactive with relatively little work.
  • New callvote menu
    With about 100 maps to vote for Coop we had to do some improvements to the callvote menu.
  • Coop_ maps automatically starting the mod
    Due C++ maps that carry the coop_ prefix in their name are starting automatically the coop mod, no scripts are required.
  • Improved and multiplayer compatible ai
    We have fixed many issues that occurred when many AI Actors where used during multiplayer, ranging from simple fixes to even new features, we could almost fix anything in the C++ code.
  • Skill/Dificulty can be changed at any time
    The game difficulty can be changed via callvote at any time during the game

Well, as you can guess there are many more new features in this new version, but we can't really list them all here.

There is one more thing we want to write about, which is the benefit for beta testers. By reporting issues or bugs you find you can gain points, these points can be traded for selected STEAM Games. YOu can read more about this on our profile.

We have a Experimental Coop Mod version available for you to try, but please notice that this version is not meant to replace the old version (5 Build 16), at least not yet!

But there where so many difficulties that needed to be worked out, that we are now having a after Christmas event. It is more fitting anyway since you have to shoot the trees in order to win.
