Ok, to start off with Bot Shots can be regular cute little figures if you want, or they can work with a rock, paper, scissors type system with symbols on their chests (as can be seen here): Then you can roll them at each other (there's no pull-back motors) & they have a pressure sensitive point on their bumpers that causes an auto-transform, which is when you get to see the symbol/number (Sentinel is a 'fist' & has a score of 980, though the number only comes into play if you have two Bots with the same symbol) EDIT: just found that the symbol in the chest can rotate ala Universe Dinobot's faction symbols, so you have a choice of any one of the 3 symbols! For some reason there was onlyone Sentinel Prime on the shelf, which was translucent, so I don't know if all Sentinels are like that or whether it's a special version etc.. He is about the size of a Legend/Legion figure in alt. mode (which is a Rosenbaum type fire-truck thing) & has some really nice detailing when you look really close. With a tap of the bumper, he then springs up instantly to a very short height. There isn't any articulation sadly, but he does resemble Kreo Sentinel's design & could fit into a G1 Robot Heroes collection. Here's some more pics: They also had Optimus, Starscream, Bumblebee & Barricade on the shelf. All in all though, this isn't a bad little novelty figure if you fancy collecting them for fun; and the game-play feature adds a bit more variety for these Bot Shots, especially for kids. EDIT: Forgot to add snaps of the packaging!
