I saw this reduced to £7.50 from £15 when I was browsing for Ben10 merchandise for my 5 yr old's birthday. I didn't expect too much, there were 2 reviews at that time and both over 4 star but neither shed much light on what this game was actually all about.

My little boy had this opened and was playing within minutes. It's kind of a plastic hollow case with holes in the top that you poke in little cards (with Ben10 Alien pictures on them) on stands. There is then a gun to slot in at either end that you fill with little balls. When you pull the trigger the balls fire into the case and hit little levers attached to the cards. When you get a direct hit the little cards fly into the air (it's very satisfying) and are out of play.

As the balls are all fired into the case it's a fairly tidy game. I have to admit my heart sank when I saw all the little balls but actually only a few go astray and you can afford to lose quite a few and still be able to play the game fine.

So me and my little boy fire manically at each other, reloading when necc - the discarded balls roll into a tray by the gun - and in theory the first one to pop all the other players cards off the case is the winner. In practice he is always the winner no matter how fab I am at this game, but that's 5 years old for you.

One reviewer states that the triggers are hard to press. It's true that my 2 year old can't press them but my 5 year old has no problem at all. It's actually one of the few games we can all play together though as M enjoyed collecting all the balls up and refilling the guns. We call her our "Ammo Replenishment Officer" :) Thumbs up for this game for us and we have never seen anything like it before. Very clever.
