Trials

Trials are challenges in the BioShock 2 Multiplayer which, upon completion, grant the user an ADAM reward. Trials require the player to either fulfill a specific task several times, or achieve a much harder challenge on one occasion. Trials have two levels: Trial and Trial Advanced. Advanced trials are usually more difficult versions of the standard trials, requiring the player to perform the same task twice as many times, and in that case are unlocked after completing the Trial version. While more difficult than standard Trials, Advanced trials yield twice the ADAM bonus than its previous version.
