Guns of Boom is a free-to-play competitive first-person shooter for mobile platforms. All you need to do is catch another player in your crosshairs and open fire. The more active you are in battle, the more points you will be awarded. To do this, you are given about 48 types of weapons to choose from. These include both assault rifles and sniper rifles. Each weapon has its own unique ability, such as slowing down time when hit in the head. Well, nice graphics will not leave you indifferent.
