Think Different is the seventh mission of EpsilonAct One campaign. While the player is nominally playing as PsiCorps, the mission is essentially a China vs. Pacific Front battle, as at the very beginning the Chinese commander will be mind controlled by the player (represented by the Soviet Construction Yard being captured by an Epsilon Engineer), who will then use the Chinese arsenal for the rest of the mission.
China has entered the war as part of the Soviet Union and advances to Europe along into Japan. The PRC command underestimated the ROC insurgents that remained in the mainland, who launched a gamble to topple Beijing. To get the Chinese cooperation, Yuri constructed a Psychic Beacon to help them pacifying the rebels, and the Chinese responded in kind by allowing the PsiCorps to take part in the Chinese assault on a Kanegawa Industries vital facility in Kagoshima, Japan, so the PsiCorps can acquire KI's technologies to support their cause.
The Proselyte quickly orders his forces to take over the outpost of the Chinese first wave of assault. However, he must strike fast and strike hard, as should the second wave arrives, the Chinese will realize something is wrong. Thus, the Proselyte knows that time and speed is of the essence during this mission. Perhaps the Japanese defenders can be forced to give up if the Proselyte pushes them enough...
We have released control over the Chinese commander responsible for the initial taskforce and had him report his success to his command. The second army has been diverted to another battlefield. This should give us time to cover our tracks. - Yuri's message
Now that the Proselyte have everything the PsiCorps need, he released the Chinese commander leading the initial taskforce from the mind control and have him reported his success to the Chinese command, which results in the second army being diverted elsewhere, giving the Proselyte enough time to cover up his involvement in the attack.
In the mission, while the player nominally plays as Epsilon, with Epsilon's UI and EVA, the Initiate survivors that emerge from their buildings are replaced by Conscripts. This is because the Initiate unit itself is not introduced (storyline-wise) until Killing Fields.
There are Jackal Racer prototypes in the northwestern corner of the KI complex, which suggests a possible link between the KI and the Foehn.
There is an Easter egg in this mission, one of the Billboards show an image of the anime "Future Diary".
