A game your family can enjoy when you don't want them seeing other violent games.
The controls have a tendency to be a tad too sensitive at first, causing your shots to miss. But, with some practice and patience, you'll adjust. There are a few other features the original didn't have, power-ups, these can sometimes save your defeat if you're able to shoot at them. They do various things, eliminate a color, laser sighting, etc.
There are a few different modes to play as well, however the gameplay is still the same, and therefore nothing different.
All & all, this game is not worth more than $20 in my opinion. I'd check the discount area from time to time to see if this drops to a low two digit or even smaller price. A good game for children and families to play, but serious gamers have way better choices out there to put their money towards.
