According to one of the Outcasts on Malta 8 ships were launched and 3 were destroyed by Coalation Forces and 5 made it to Sirrus System. Which makes me wonder wre the other 6 are. Did they even finish producing the ships or were they launched to another galaxy.
Game made it to E3 in 1999 and was not released till 2003. That is a 6 year gap. They could have made a better storyline and made the ending a lot better in those 6 years without all the question marks and leaving a huge cliffhanger ending.
