Onslaught is an unofficial modification for the game Homeworld:Cataclysm. It is a tribute to the Homeworld series using almost all of the un-flown ships in Homeworld and Homeworld:Cataclysm. These include the Kadesh (inc MS), the HW Ghostship, the JunkYardDawg, most of the HW Derelicts, the Nomad Moon and more besides. Onslaught unites these ships and creates an entirely new game. The Beast in HWC provides an excellent excuse for this bizarre mix of ship types!

Version 4.1.9 replaces the short-lived v4.1.8, which had a signifiant bug. This new version has been fixed. Don't be fooled by the version number; this is a major release, and is the final version. Several ships have been re-textured, a number of bugs have been fixed, the hints section has been improved, new maps have been added and the game play has been overhauled in response to the comments of experienced Cataclysm fans. Visually the most noticeable changes are to the Beast Carrier and Beast Battlefield Frigate, both of which have been faithfully re-textured as repaired versions of the original Homeworld Derelicts, and the replacement and reworking of mothership support modules on both sides. Onslaught is now as faithful and complete as I can make it.

In order to play the Onslaught MOD you'll need to have Homeworld:Cataclysm already installed and working. You will also need to have the latest patch installed. If you do not already have it the patch can be obtained from Sierra.com. In order to play Onslaught against an Internet or LAN opponent you must both be using exactly the same version. You can tell which version you currently have when you run Cataclysm with Onslaught installed; on the main game menu you will see the Onslaught version number. This MOD is much more demanding on your PC than the original game ever was. If you wish you can improve the performance of the game using special command line options. Click here for full details of how to improve performance.

The actual MOD is a single file called "update.big". It's very easy to install.

1. Unzip the "onslaught4_19.zip" file.
2. Run the "onslaught4_19.exe" file and extract its contents to the destination of your choice.
3. In your existing Cataclysm folder there is an "update.big" file (about 300Kb). Rename it to "oldupdate.big".
4. In the Onslaught folder there is another "update.big" file (about 21.2Mb). Copy it to your Cataclysm folder.

Assuming you’ve followed the installation instructions:

1. In your Cataclysm folder delete or rename the Onslaught "update.big" file.
2. In your Cataclysm folder rename the original file from "oldupdate.big" to "update.big".

In order to play the MOD you'll need to know the gameplay of the original game, most of which is applicable to Onslaught. Read the original manual, and use the TUTORIAL button on the main game menu with Onslaught installed. The Onslaught MOD makes a lot of changes to the game, most of which will be obvious with a little bit of play. However, there are some things you may not notice. Be sure to click the HINTS button on the main game menu to find out more.

I haven't had any problems reported before. Does your installation of Cataclysm work without Onslaught installed? What version of Windows are you using? If you're using Vista then I don't know what to suggest but I do know other people have played using it. If you're using XP, have you checked the downloadable notes on compatibility?

Also, if you've been trying other mods make sure you've removed their files fully before trying Onslaught.

I am an old time fan of the Homeworld series and really appreciate seeing such a great mod of my favorite theme. The sheer quantity of new ships is very impressive (and I've just started playing)! The action is intense - can't snooze on the job! :thumbup::thumbup::thumbup:
