Batman Street War
I know this is completely new game, but I couldn't help it looking for the similar game with the very same cover animation which has been obviously 'borrowed'. And I've managed to find it. The original game in question is Voodel's Batman Stunts where you can see the identical figure of Batman sitting on a bike with his cape waving on the wind. Basically that is all when it comes down to similarities. The first one was about doing stunts for points, while this game is about avoiding obstacles and shooting the bad guys.

To be honest, when I tried to play this game I realized that the player could easily move his mouse away from the game screen and click on something in the near, which is something nobody wants to happen. Therefore, I wasn't really happy about having this game on site. On the other hand, when it comes down to flash games, we can't allow ourselves to be picky these days, so I just hope the player would rather choose to keep his mouse constantly pressed, which reduces the chance to accidentally click on something you didn't want to in the first place. I think that constant shooting is way better strategy, and is good strategy for the game itself.
Enemies & Obstacles

There are plenty of guys in cars who shoot at you and want you dead. Batman is completely aware of that, so he never enters the streets of Gotham without some cool gadgets and guns mounted on his precious batmobile. Nevertheless, his powers have limitations too. In the top right corner you will see a bar which tracks the health of your car. When it gets down to zero, the game is over. You can retry, of course, as many times as you want. It's endless, remember?
One of the first enemies you will face are black limousines coming at you. Those cars are obviously armored because one missile is not enough to make them stop. Good thing about them is that they don't shoot at you.

There are also other cars, which do not threaten you directly, but if you bump onto any of them, your health gets decreased as well, so make sure to avoid anything on your way. This cars act almost as static obstacles.
Than there are small green racing cars with mounted machine guns which I find if not impossible to avoid, than at least extremely dangerous. Many of my attempts, while playing this game, have ended just about stumbling upon one of these guys.
Not everybody are trying to kill you out there. You will certainly notice big yellow, I would say golden cars, which you can use as jumping ramps. You can use them to jump into the air and shoot at helicopter above.
