What a HUGE waste of time this mission is..
first off its only 1 HOUR long.. you can maybe do 3 or 4 if you are lucky..
second, out of those 4 you will FAIL every single one
i paid 500 zen for a fighter.. i ran at least 10 vault missions.. and have not won one yet..
it seems there are too many enemies.. or reriks ship is too weak or not enough time.. its always something..
one time i thought we won.. we got to the end, killed the big ship.. then the time just ran out and we failed.. there was no bad guys left alive..
