Chuck's Reviews Transformers Rise of the Beasts Optimus Prime 2 in 1 Blaster
 

With a new movie line, there's usually some role-play product that ties in. once again Hasbro uses their Nerf brand to bring us an Optimus Prime figure that transforms into a fun blaster. Transformation is actually surprisingly involved, especially in the arms which I appreciate, moving beyond a simple one-step or flip-change transformation. While not for most collectors, if you're looking for something fun for an office battle this fits the bill nicely.
