This is one of the best flash game I have ever played. It is a first person shooting game. The violence level is okay, I would rate it 6/10 for violence (10 being very violence).

I like this game because the level become more challenging and you are forced to switch between different guns when you are faced with a lot of enemies. Graphics is not bad and the gun sound is good.

You do not move around, therefore you only control the mouse cursor to shot. End of every level you will be given some money / soul to buy for more better items.

This is one of the top flash game I have played so far in term excitement.
