There was a whole crap load of stuff that didn't make it past the beta release.
And it wasn't the Hurricane...it was like...flak...in missile form...it was dumbfire but packed more of a punch than anything out in R1.
And one of the things they took out was the Vasudan Hammer of light Carrier...whatever it was called...it was big...scary...and...scary...Also the mission against the Nemesis was different...atleast I think it was...Plus

of filler missions got cut, probably just to move the story along

faster.
And the last mission with the Gigas was the most changed mission...It's not the little wee, recon with these two destroyer dealie...no...It was

cooler.
Last Mission From the Beta:
GTVA blockaded a jumpnode, you had to protect 3 destroyers (I think it was 3...) from shivan bombers and fighters while the Capships nuked cruisers, corvettes and Destroyers as they came through the node. It ended with the Gigas jumping in and all the destroyers buggering off. (pansies...)
The new mission is

better, but that mission was cool in

of ways...it's not everyday you fly with the best anti-bomber missile...my god...it was awesome...Now that I think about it...it had a nuke symbol on it...but it was a dumb fire missile...like the Tempest, but 15^100000000 times better.
