Gun runner is a step away from the new games focusing on complex storylines, and insane objectives. This is taking a step back, back to doom, and not the third. It is arcade like action in it's greatest glory. It will have fun gameplay, but still challenging. Loads and Loads of weapons. Different Settings too.
You are Marcus Flessen. You work for a company under the United States government known as S&D, better known as Search and Destroy. This is a secret military company. Having access to the best of technology, you are sent into normally near suicidal situations. Usually your objective is to make it through multiple areas of a building, or situation of buildings. (Levels) At the end, there is one main guy you are supposed to S&D. You will be sent in with a near neverending supply of ammo, you wont run out anytime soon. Sound easy? Well, thats the problem. The enemies are masses, and heavily armed. They are smart, too smart. You can't sneak through either. Run and Gun Marcus, Run and Gun.
