All of the online achievements in this game can be done in Private Matches. The multiplayer side of the game is on Disc 2 of the Retail copy of the game. No downloading or installation is required.This achievement can be done either in the Invisible Predator Online game mode or the Hunter, Hunted game mode. I recommend the Hunter, Hunted game mode as it is the easiest.Lobby Setup
For this achievement you will need at least 7+ players including yourself. If you have dummy accounts, that might be a recommendation to ease the congestion.
Whoever is the host needs to go into "Create Private Game" from the Main Menu and make sure Mode is Inv Pred Online (Invisible Predator Online) or Hunter, Hunted and the recommended map is Chemical Plant
. Keep "Map Rotation" Off
and then click "Start Game".
Here you need to use your
and invite your group into the game until it is full with the people. Once you have enough people you can start the match. If anyone get's disconnected during the match, the match will continue but they cannot return to the game as invites will be disabled.Boosting Method
If you are doing this in Hunter, Hunted game mode, you can easily end the matches faster as everyone will only have 1 life each instead of 30 shared out. This will make the achievement less confusing and you only need 7 people to do it instead of 8. The drawback though is you will only get 7 minutes to go for the achievement instead of 15 minutes.
You will have to either be Batman or Robin. If you have 8 people then one of you will spawn as Robin as well as Batman, giving 2 people the opportunity to go for the achievement.
For this achievement you will need to all meet up somewhere on the map and whoevever is the Hero needs to get a unique kill on each of the 6 opponents that are in the match. 3 of the opponents have to be Joker Team and the other 3 have to be on the Bane Team. The achievement will pop once the requirement has been met, but it is known to be glitchy and will require another attempt from scratch if needed.List Of Attacks You Can Do As Hero Which Credit Towards Achievement.

, there is a method that can be applied of you want to have certain people on certain teams before your match loads up. This applies throughout the multiplayer of the game.
From the main menu, if you go to "Options" and then select "Game Options" you should be given the option to choose your "Faction Preference". Originally it says None, but you can change this to either "Joker" or "Bane" so that you have a high chance in joining either of the two teams you wish to be on. If you are wanting to be "Batman/Robin", simply keep this as None and choose "Hero Opt-Out" as "No". Get everyone else to choose "Yes" and this will give you a high chance in becoming "Batman/Robin" for the round you are playing on. However even though you have chosen these team members doesn't 100% guarantee you will be on that team. In addition at the end of the round, people can still "Opt Out" & "Opt In" if they want to become "Batman/Robin".
You may also get this achievement at the same time if you manage to do all of these moves within a 40 second duration...
