31- G Corporation, Millennium Tower Heliport (Kazuya) Note: You will fight Anna and goons again first, then survive an endurance round, and then Kazuya will show up.

32- Mishima Zaibatsu, Central Subway Line (Nina) Note: You might not have enough time to take Nina out in the usual manner so your best bet is to knock her off the train.

34- Mystic’s Village- (Endurance round with Zafina who will be unlocked)

35- Azazel’s Temple- Final area, no characters unlocked here but you should complete to unlock the remaining bonus stages. Your boss battles will come in between gameplay and are as follows.

Kazuya (He makes a hysterical comment on the Tekken story here)
Azazel
Alisa
Jin (Of course ugh…)

This marks the end of the campaign and you will see the end cutscene. After which your options are the following…

Note: I will list these in the order I feel is easier but you can do them however you feel.

36- Kigan Island (How to unlock Yoshimitsu) Note: To unlock this stage you must re-enter Campaign mode and select Hard mode (don’t worry no progress will be lost). Re-enter the ‘Abyss Gate’ (Steve) level. There will be a box immediately to your left. Break it open and fight the ninja inside. Grab the key he drops and finish the level. After which you will unlock the aforementioned area. You may switch back to Normal mode if you wish, and fight through a long Manji Fortress til you get Yoshi.

37- Subterranean Pavillion (How to unlock Mokujin)- Re-enter the 16th Archeological Excavation Site (Leo) again after beating Campaign Mode. You MUST be on hard mode. Complete the stage and Mokujin’s stage will be unlocked. Note: After playing through this stage 3 times I’ve concluded that the best items are dropped here ALOT more often then other stages!

38- Nightmare Train (How to unlock Devil Jin) This stage appears immediately after clearing Campaign mode. I STRONGLY suggest having good equipment (Preferably a High drop rate) and alot of patience. You fight a slew of Azazel demons and do so until DJ finally appears. Note: I’ve made it to Devil Jin and it seems you fight 40 demons before him after observing the fight count at the end. He shows up with 2 demon guards so be prepared!
