I remember all the weapons were used, just not at which point. I am sure that the HML was used, if only because I remember Camille using it as a spear, which is one move present in Mobile Suit Gundam: Gundam vs Zeta Gundam.

Of course, all I care about are the moves he uses when the Zeta Gundam activates its Biosensor, like Sword of Rage and Waverider Crash.

On a random note, I've seen all of Victory Gundam and yes, it has a much higher mortality rate. The basic rule is that if there's a character that's a woman, she's most likely gonna die. There are about three exceptions to this rule, though one of them didn't come out completely unscathed.
