Guns of Boom PTS is an FPS where two teams go head to head in fairly large settings. Both the casual style of the action and the graphics are similar to great PC classics like Team Fortress 2 or the more recent Overwatch. The thing that's unique about this version is that you'll be able to test out new features as they're introduced in the main title before everyone else. With this app, you'll enter a PTS (Public Testing Server) to test each improvement first hand in beta mode.
One of the best things about Guns of Boom PTS is its control system. You'll be able to move your characters freely around the setting using virtual joystick on the left, while you use the right joystick to aim. However, you don't have to tap any button at all to shoot. As long as the enemy is in your sights and within range of your weapon, you'll shoot automatically.
With the experience you gain as you play, you'll be able to unlock new content. The most interesting content to unlock are weapons, of course, but you can also acquire new character skins to customize your avatar.
Guns of Boom PTS is an excellent multiplayer FPS, which has a perfect control system for touchscreens and nice graphics. It's a great title to keep in mind for fans of shooting games who are looking for a bit of competition.
