Ben 10 Gang War

You move Ben left and right, firing his Omnitrix energy blasts at waves of gang members that approach from both sides of the screen. The main objective is to clear each area of enemies, culminating in a fight against a gang boss. You have to manage your positioning to avoid getting surrounded, and sometimes pick up health items that drop. The pacing is constant, with little respite between enemy waves, which keeps the difficulty noticeable. It feels like a hectic, back-and-forth shooting gallery set on a single city block.
