The game later recieved an update in 2010 in the form of 戦闘機 Sentoki 4: Unleashed, which added new characters and stages, as well as rebalanced some characters and gave them new unlockable outfits for customization. Released for Arcades (ACS System 202: ENDYMION), PlayStation 3, XBox 360, PlayStation Vita and the Samsung Zeo, as one of its launch titles.

Gameplay
The game mostly plays the same as the previous game, though new gameplay mechanics have been added. The Custom Chain system allows players to create a custom chain of up to 15 attacks. Each character has an attack that can start a custom chain, and after this attack has been performed, the player cah then connect a set of pre-programmed strikes by pressing a direction and Punch or Kick (each character has 9 kicks and 9 punches for custom chain, corresponding to each direction) to create the custom chain. However, players cannot repeat the same move lest it automatically stops the combo and restricts their movement for one and a half seconds, leaving them wide open for counterattack.

Other new gameplay mechanics include Guard Crusher moves, which are attacks that leave the opponent vulnerable for a certain amount of time when blocked, forcing the opponent to use alternative defense methods like countering,, and the addition of wallstun throws, which are throws that can be used while the opponent is under wallstun, and can be used as juggle enders.

The game also includes new real-time clothing effects, with some stages including water, mud or certain other elements which can be reflected on the fighter's body as the fight progresses.

Story
As Kei Ikushima reaches the finals of the Sentoki tournament, Ranzou Kihara, who was watching over the tournament, decided to unleash K1, a clone created in Kei's image and infused with all of the fight data collected by Orion, upon her.

Kei was able to defeat the clone and win the tournament, until Ranzou, not liking the results, decided to restart the match.

As the match got restarted, K1 proceeded to attack the battered and exhausted Kei in cold blood, delivering vicious blows and strikes, which incapacitated her.

She was about to be killed by K1 when Shin intervened and fought with the clone. He was eventually able to defeat K1, but Kei barely survived after the injuries she suffered, and was sent to the hospital.

Meanwhile, a mysterious man who goes by the name of "Nixon" watches the entireity of the tournament through some of the TVs displayed on a surplus window.

All alone on the streets, Nixon has no memory about his past, and has lived his life as a vagrant, walking the streets of Tokyo and occasionaly fighting as a shoot boxer.

However, despite his amnesia, he seems to recognize the face of Ranzou Kihara.

He dosen't understand it either. He just felt something... familiar about him.

Almost a year after the last tournament, Orion would announce the next Sentoki: Global Martial Arts tournament. Upon hearing news about it, Nixon decides to enter the tournament, thinking that Ranzou has all the answers to his past.
