Your objective is almost always to take down the rival team. The classic game mode in Brutal Strike is the same as the one in Counter-Strike, with some practically identical settings like cs_Assault and de_Dust2. That said, you can always adjust the controls whenever you want, from the setup menu. On the right side of the screen, you'll also have the buttons to shoot, crouch down, or use the weapon's telescopic sight. In other words, with your left thumb, you can move your character and with the right, you can aim. The controls in Brutal Strike are typical for the genre for mobile devices. Plus, you'll also find new game modes available. The main difference between the two is that, in this version of the game, you'll find a lot more blood and violence. Brutal Strike is a first-person action game that's similar to Counter-Strike 1.6, offering a nearly identical experience to the legendary game from Valve.
