Artificial Mind and Movement (often abbreviated as A2M) was a rename of Behaviour Interactive that lasted from 2000 to 2010, during which period they primarily focused on making licensed tie-in games.
In November 2010 they changed their name back to Behaviour, due to their increased output of non-licensed games... and because "A2M" can be easily interpreted as "ass to mouth". Seriously. Why they didn't just use something like "AMM" as an abbreviation is anyone's guess.
