Rasternauts

A pixel perfect way of life is under threat when a scientific experiment gone wrong uncovers a new dimension composed entirely of vectors! Take control of any of 7 playable characters, each with their own unique weapon, to run, jump and shoot your way through over 40 levels to save your bitmapped buddies, hold back the vector invasion, and save all of raster kind. Rasternauts is an 8-bit run and gun platformer inspired by such games as Metal Slug and Contra. Source: The Developer Website.
