<P> The fighting gameplay is based on that of Dead or Alive 3, with several changes . Like in the other games in the series, fights in Dead or Alive 5 are based on an interruption triangle system in which strikes (normal attacks) beat throws, throws beat holds (strike interception attacks), and holds beat strikes, all of such counterattacks causing extra damage . Tag team battles from the previous DOA games have been retained . The fights take place in interactive and now more highly - destructive arenas . The game's characters are rendered in much more realistic visual style than in the previous titles in the series, including new details such as the fighters getting sweaty and their clothes getting dirty during the fights, costume - specific breast physics and semi-transparent clothing . </P> <P> A new feature called Power Blow (a triggered powerful attack that can be executed when a character's health is below 50%) enables the players to knock the opponent character away in a selected direction . Characters can be thrown into the series' signature Danger Zones or over a cliff in the multi-level stages; this initiates another new feature, which is a cinematic quick time event called Cliffhanger . With Cliffhanger, if a character can grab onto the stage at the last moment before falling into a lower level, an action sequence is activated where the opponent character can make an effort to inflict even more damage if the attack succeeds . The game's Critical System features Critical Stuns (after having been hit with specific moves, opponent characters get stunned and are unable to block, but can still perform holds), Critical Combos (striking a character in a Critical Stun state can prolong the amount of time they remain stunned, but the damage that can be inflicted this way is limited) and Critical Bursts (specific strikes over the damage limit of successful Critical Combos that leave the target character completely defenseless for a short while). </P> <P> Dead or Alive 5 is set two years after the events of Dead or Alive 4 and the destruction of the DOATEC corporation's TriTower headquarters . Helena Douglas has undertaken the task of rebuilding DOATEC but wants to use its technology for peaceful ends . Helena dissolved DOATEC's Biotechnology Division, stopped the Military Division's biological weapons projects Alpha, Epsilon and Omega, fired all members of Donovan's faction, and announced that she intends to hold the Dead or Alive Tournament 5 (DOA5), hosted by Zack, "to show the world the principles and philosophies upholding the new DOATEC ." </P> <P> The game's Story Mode is told in the form of one long sequence, similar to the Chronicle Mode of Dead or Alive: Dimensions and presented in "hyperlink cinema style" for more character and stage interactions . It is not told in chronological order and is instead divided into a series of interconnected chapters following various characters and showing the events from their respective perspectives . There are two main storylines, one telling the story of the fifth tournament, and the other one centered around the hunt for Alpha - 152 . Characters from the both storylines often interact with each other in minor ways . </P>
