The basic philosophy behind this mod is to use all the "unflown" ships in Homeworld and Cataclysm. Both the Somtaaw (good guys) and the Beast's (evil Enemy) fleets are replaced by the single player units from the original Homeworld: the Kadeshi, Turanic Raiders, the Homeworld Derelicts, the Junkyard Dawg, even the Bentusi Trader Vessels; and from Cataclysm the Nomad Moon, the doomed science vessel Clee San and a lot of the spectacular bases and edifices created for both games. Its impressive and even better - has actually had much attention lavished on it to make it playable in netgames. About the only downside is that some of these spectacular units are so big it can get tricky to pull the camera back far enough to see everything!

This is quite a lot of fun: to go with the bigger, more pumped up ships, there's a higher unit cap and you can build an extra carrier. Deploying hordes of Rapid Beam Frigates or Plasma Stream Frigates (think rapid fire Plasma Bomb Launchers) is like pitting strikecraft clouds against each other. In the middle of it loom the massive planetoid like Bezerker (pictured) or the Battlecruiser (one of the Homeworld single-player derelicts). Instead of the Beast's infectious Cruise Missile, you now use Homeworld's Headshot Asteroid! Everything is beefed up, seems to have multiple weapons that shoot lots, and makes for some pretty awesome firefights. Even Scouts use ion beams! Watch out though - explosion damage from the super capital ships can take out half your fleet...

The Onslaught mod ships with 200 custom maps and most of the original single player missions are still playable. Not all of them though, and the mod starts you on Mission 12 as a result. Current ("Absolutely final") version: 3.5.

A single page holding pair of tiny Cataclysm tweaks and a simple Homeworld2 retune called the Fair Play mod. The Cataclysm mods are:

Reverse Weapons Concept:
reverses the roles of Ion Beams and kinetic weapons (think high tech bullets), so that Beams are now weak (anti) fighter weapons, and the turrets are now primary armament, mostly replaced by the Plasma Bomb Launcher. In particular there's now an artillery piece: the Plasma Bomb Array Frigate can bombard targets 14km away on a Cataclysm map. called the There's a few other adjustments, like the Beast's Infection Beam and some ship stat alterations. Current version: 3.2

Externally Built (EB) Mod:
This is an older version of the Reverse Weapons mod, but with an alteration where Frigates are treated like Super-Capital craft: they can be constructed underneath the Mothership like the Super-Capital vessels but can't dock - apparently to stop the Beast player from quickly acquiring the technology too quickly. Building times for much shipping has been halved as well.
