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.Lobby Setup
For this achievement you will need at least 5+ 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
You can easily work on this achievement the same time as...
You will have to either be Batman or Robin. If you have less players within the group only one of you will spawn as Batman whilst the rest will either be on the Joker Team or the Bane Team. If you have 6+ 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 get at least 4 people within the Joker/Bane Teams to squeeze within each other like a sponge. The Hero will then go nearby and then equip the Explosive Gel by pressing
. They then need to hold down the
button and then press
to place the Gel on the ground.
When everyone is nearby and in position, the Hero needs to step back and then hold down the
button again. When ready press the
button to detontate. The Gel will explode and if done correctly the explosion should kill at least 4 opponents, giving you the achievement. If you didn't get it, you've got less than 40 seconds to take down some opponents in getting credit towards the achievement before the counter resets.
There are other attacks Batman & Robin can do in the game without meleeing but this is known to be the easiest.

, 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".
