Wolfpack

Wolf Pack was a virtual training mode in the third stage of the Animi Training Program.

It revolved around assassinating non-player characters (NPCs) with the co-operation of other Abstergo recruits, and was structured in sequences. There were 25 sequences in all, each which became increasingly more difficult as the recruits progressed.
