Everytime I play the Metropolis level, I no longer hear, “That thing is really starting to piss me off! Marines, time to kill us a scarab.” I haven’t heard it for some time whereas I heard it constantly on the old Halo 2. You didn’t even have to be near him to hear it as he’d say it over the radio.
Probably wasn’t “removed”, could be some oversight bug causing it not to play…
Currently there is a bug in H2A where radio volume decreases the further you are away, so a lot of lines just don’t play.
in german it still plays the line
