Um, what...? Rev was never on 3DS. You might be getting confused with Aveline's "Liberation," which was originally designed for the PSP. Also, I don't get where people are calling "Revelations" short. It was as long and epic as any of the other AC games, and especially longer than AC1. This New York is a full-sized city, not the burnt-out ruins we saw in AC3. It's the biggest city we've AC-ed in since Constantinople. You won't always be a Templar. According to the Ubi page, you follow Shay's descent into darkness, beginning as an Assassin before turning rogue. It's possible you might even find yourself empathizing with his reasons for the heel turn. Ubi calls it an "air rifle," and yes, it has several attachments.
