A friend of mine that lived down the road had this game, which of course made this game more interesting to me due to the fact it was "new". The gameplay in this game basically revolves around "saving the children". The children are hidden throughout the level, behind doors or in cars. Whilst saving them you have to of course dodge the enemies, they can't hit you or shoot you. And every 3 stages or so you have a boss fight.
What I find the most frustrating about this game is simply the fact you have to check every corner of the map for the children, which is made harder because you can't really tell which doors or cars you've already checked. So if you are missing one child on the level you have to go throughout the whole thing again checking every door in case you accidentally missed one. Regardless, I still finished this game. :)
The music in this game contains some memorable Michael Jackson hits which kind of makes playing it not so bad, especially when compared to most music in SMS games. The graphics are also fairly decent.
