I have long suspected there is a problem with the scoring on Halo 2. I've tried to search the official forums-not easy as they don't, as far as I can see, provide a search option. Several times whilst playing slayer in the rumble pit, I haven't been awarded with a point for a kill I have made. Last night though, I had 18 kills, thought "great just three behind the leader". Next life, killed another before being killed, and my score was down to 15! No suicide which I know reduces your score. I think it may be a lag issue. A couple of times I have noticed the scoreboard flip down to a lower number of kills before flipping back up to the right total, almost instantaneously. Does anybody have any experience of this?
