@i-NormI explained how they get it on jump in the other thread from the ship, and I agree, it still isn't fair.
That said, I got the sword in a match just now and was so excited since I heard how broken it is. The block feature did nothing to shield me from bullets, I still died in 2 hits. Also, when I used it on the enemy the sword went right through them, doing no damage at all. I'm wondering if the people using it the way described here aren't cheating or exploiting a glitch, or if it glitched when I had it since it was worthless when I tried using it.
