it is not a bot lobby because the clan tags of the enemy are not [3arc]. It is multiplayer because how else would he get a 12 k/d?
It could be a custom xp lobby and there was a way to code 3arc off bots. Pls do some research before making judgement and discrediting peoples post. Not to mention these ppl could be boosting as well or used another account that he ruined the stats on as host to be linked to the worst players online in the matchmaking system. i mean seriously he only has 3771 kills 12+ k/d and only 17 hours played prestige 1 lvl 50 seems fishy to me that or he is one of the best bo2 players.
