Remove it !
Normaly we dont need Hive as teleport (movement chambers are smarter for choose and tactic), this thing absolutly changes the game - and it's bad. "Friendly fire no longer makes a hive available for teleportation." - it's logical when aliens hit hive and you can't teleport to it - that's OK, but if MArines attack hive - aleins has to has posibility teleport there, no other chances to get get Hives place back!!!
I'm playing NS starting from previous version of HL,and this Hive think is bad for the game strategy - think about it.
