I just wanted to mention that to me at least, it seems as though the Breen Cryo Grenades that get thrown at you by the A.I. seem a little too powerful. At least for normal difficulty. One grenade wiped out my whole away team After I was done cracking up, I though to myself, that sure was a powerful grenade. I do not know if the ones you get as a reward are as powerful, if they are, its time to freeze some borg!!
