Let me explain how it happened - The game was 1 flag meaning 1 team attacks other team defends...
Now what happened is the defending team(the spawn killers) screwed up all the possible respawn points for the attacking team making them forced to be respawn in that 1 room... wich gave them those cheap but easy kills(like you saw in video)
and also as much as it was cheap, the guy that got the killimanjaro is actually a pro... i saw another of his video and he's pretty crazy
Oh and BTW the people he played against were probably not noobs... because?the situation they were in...??they didnt have a chance... poor poor them
