The main Headquarters of the Mishima Zaibatsu company. The Tower is full of guards and has an Intruder Alert - the alarm will be sounded if anyone enters without permission, if the guards weren't enough, NANCY-MI847J is always on-guard too. With Jin's whereabouts unknown, the company is lacking a Head, it's only a matter of time before it's reign of power comes to an end...
A large research facility owned by the Mishima Zaibatsu, hidden away in the mountains. The place is now in ruins, only a few pieces of equipment left there and who knows what chemicals that have not been disposed of properly...
