Tekken 5 is credited for taking the series back to its roots. It incorporates a faster, more fluid fighting system, improved graphics, returning characters, and some of the Tekken series' trademark infinite stages. New to Tekken 5 is the crush system which affects the vulnerability of a character while they attack. For example, a move with jumping properties, such as a hopkick, will be completely invulnerable during most of its animation time to all of an opponent's low attacks.
It also retains its wall juggling concept from Tekken 4, but the element is effectively less easy to abuse and easier to defend against. The home version is a collector's edition of sorts, as it includes the arcade versions of Tekken, Tekken 2, Tekken 3 and StarBlade (as a hidden game). Tekken 5 also allowed players to customize their fighter for the first time, allowing them to change the colors of their outfits, buy additional costumes (only available to a few characters), and equip them with items by using money gained from playing the Story, Survival, Time Attack, the side-story Devil Within, and Arcade Battle modes.
Tekken 5 includes a fighting minigame in direct lineage to the Tekken Force modes in Tekken 3 and Tekken 4 called Devil Within. This minigame follows the adventures of Jin Kazama as he searches the G Corporation in search for information on his missing mother and other answers. Being somewhat story oriented, the player is not permitted to use their own choice of characters like previous iterations. The game also uses a limited button system, incorporating a Block and Jump button as well as sizing down the attack buttons to simple "Punch" and "Kick" buttons (though, some of Jin's fighting special moves can still
be performed such as his Demon's Paw). Along with fighting various Jack models in the mini-game, the player must pursue minor key quests to proceed. This mode is one of the two ways to unlock the playable version of Jin's Devil incarnation, Devil Jin.
