Minigore is mostly about walking around and kill bad guys that are becoming bigger and harder to kill as you progress. It is well developed with sounds, scenes, and graphics.
The nice thing about this game is that it is extremely easy to navigate using the virtual joystick, something I cannot really say about too many games.
In addition, the weapon sounds, the automatic shooting are just too cool to ignore.
So as this game has recently gone free for a limiter time, I recommend you give it a try. It's fun, and hey, this is why I'm writing about it straight from my iPhone, to be able to continue playing.
