Horizon Shift has is currently out on Steam. Marketing itself as a unique blend of a classic arcade shooter and a platformer, it promises a ton of new ideas by integrating the two genres.
The claim can be seen with a bit of skepticism. While the game does appear to be a good retro shooter with platformer mechanics integrated into play, it's hardly the first game to do this. While the game can be fun, there's nothing too new about the experience.
So for those who like platformer and shooter blends, Horizon Shift provides a quality retro style game. But don't get into the game expecting the already used formula to heavily deviate from the norm.
