And not only that, but also that management is not so easy, but simulating the inertia and the associated details, which further complicates the process of aiming, and survival in General. Hit the enemy? Get the number of points and make no mistake, for his place immediately announce new, and over time their number will grow, and their attacks and the trajectory will become increasingly dangerous.
