the release of Homeworld, director Alex Garden had this to
say about the third NPC "pirate" (or P3) race:
no one knows nothing about … they’re this extremely
mysterious extremely powerful race that you’re almost
unable to defeat and they’re completely evil. They’re
like the great evil of the universe; they have no motivation
that you can discern, they just come in and basically kick
your ass, and do whatever the hell they want to and then
they leave. And you’re left baffled and not understanding
why this is happening. But you hate them, you hate them…
You really hate them and there’s nothing you can do
because they’re so much more powerful that you. But at some
point in the game you might have a chance to get your
revenge, if you’re lucky."
starfish-like design sketch was released in some of the
previews, and it
was later revealed that the name of the P3 race was
"T-Mat." Unfortunately, word got out before
release that this starfish design would not be in the game.
star-shaped beast was the concept design for the T-Mat
pirate mothership, but technical limitations forced us to
axe it. A pity, it would have been fab." -Rob
Cunningham, Art Director
limitations apparently involved the large spaces between the
starfish arms and a conflict with the collision-detection
system. A replacement for the star-shaped ship was designed;
it was more organic looking, and had stalactite-like spires
that detached as separate frigates. Unfortunately, this
version was also not used, and there are no T-Mat missions
in the released game.
the T-Mat did make it into Homeworld after a fashion. The
revised design for the T-Mat Megaship was used as one of the
Galactic Council Member ships hyperspacing into Hiigara space
with the Bentusi after
the death of the Taiidan Emperor. (Actually, all of the the
hyperspace signatures you see except for the Bentusi's are
Megaships, but only one materializes before the scene fades
There are also entries in the .big file for a T-Mat Frigate
although there are no models for them, we have the stats.
Both are similar to the Megaship; they have ludicrously high
hit points and a single continuous-beam Ion Cannon.
