These commandoes work for Haihead.
Within the ruins of the lost world, an unexpected event has occurred: one of the scouting parties found a pair of survivors, teenage siblings who have not yet been corrupted by the mind control. A brother and sister have been found in a state of almost complete exhaustion and it was later said that mere hours of delay would have caused their demise.
After their recovery, the two would begin to value the precious time they've been given, figuratively and literally. Taken to the Bastion's site they've begun their training using the place's unique condition and during the few short years, they've acquired much more experience than the average soldier could in the same period during the old times. It is said that among all the residents of the Last Bastion, these two understood best how important the time given to them is the most and made the best use of it.
Alize and Fin have givne themselves a mission of their own: together they march forward to eliminate any signs of threat on the path of the Haihead's counter attack. Alize uses a blast rifle which relies on similar technology that is used to manipulate the superpowered steam coming from the trenches connected to the Blast Furnace. These blasts released at high pressure can blow up enemy vehicles and tanks in a matter of seconds. On the other hand, Fin has mastered the use of a custom automated sniper rifle, with which he can kill multiple enemy troops at great ranges in short intervals. The weapon has to reload after a series of shots, but even then Fin can kill to some extent.
On the battlefield, Alize and Fin are inseperably fighting side by side. A unique nanotechnology design has been created to allow them to support each other. As long as the siblings are close, they will heal each other and be able to withstand quite an amount of damage.
