The gameplay of Dead or Alive was unique at the time of its debut because it featured different choices in gameplay than other early 3D fighting games. Its most defining features were its speed and countering system. Dead or Alive put an emphasis on speed, and relied more on simplistic commands and quick reaction time. Furthermore, its countering system was the first in the fighting genre to utilize different commands that corresponded to each type of attack. There are two kinds of holds, an Offensive Hold and a Defensive Hold; the latter are executed by holding back or forward on the directional pad along with the guard input to either force away or counter-damage an opponent. The game also introduced an environmental system of the "Danger Zones" that surround the outer edges of the fighting arena (depending on the options, it can also completely consume it) and can send an affected character in the air so the opposing player can execute a juggling air combo. However, this can be avoided with a defensive roll.
