User blog comment:AgentG231/What specifically is the bug in the Animus 1.28 that made Altair can't swim?/@comment-3251634-20130426230122

A lot of the details about how the Animus works have been really inconsistent over the years. You're really better off not even trying to follow. The creative direction on the games has this pointless need to explain everything with the animus, or other things. Which is why there's never any HUD in the modern day, and Desmond is followed by a friggin' RC helicopter that records him during his few missions in AC3. It's also why we're never allowed to remove weapons, or armor. It's silly, and personally I think it really holds the games back. Often times the developers just won't do certain things that would be good because it conflicts or can't be explained with the "lore" of the Animus.
