Has happened a few times. Not many, but enough to be annoying.
You have a good team, it's all going well, you get the optional, you get to the last room with the queen. Everything is going perfectly, no-one dies, the borg fall like flies and then BAM!!!! the queen hits you with her super uber secret weapon!! [Borg Cut Scene Instadeath Superweapon MK XII Dmgx1000 CritH, CritD] You are frozen, unable to do anything as you watch in horror as the floor turns green around you and your team mates and you are all dead and have to start again... So yea... can we get rid of the mid battle cut-scene at the end of Hive Ground please?
