In the overview it says Players "4". I believe this is incorrect as it is no more then 2 players. As mentioned, the 20 secs is a little to short for each round (2 rounds per player per mini game). My 6 year old son really likes the game and as he is not old enough to shoot zombies, this works well for him. The game does adjust to your skill so when I play with my son I get more and faster targets. I say if you like shooting games and want to include younger kids then this is a good pickup.
