These commandoes work for Haihead.
Within the ruins of the lost world, an unexpected event has occurred: one of the many expeditions to the other side has come across a pair of survivors: young siblings, whose minds have not yet been corrupted. 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 Last Bastion, they've begun their training under the place's unique conditions, and during the few short years they've acquired much more experience than an average soldier could in the same period of time in the past. It is said, that among all the residents of the Last Bastion, these two understood how important the time given to them is the most, and made the best use of it.
Alize and Fin have given 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 tech that is used to manipulate the devastating steam erupted from the Blast Furnace's trenches. These powerful controlled blasts can blow up enemy vehicles 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 time. The weapon has to reload to reach its full firing speed after a series of shots, but even then Fin can continue to kill if necessary.
On the battlefield, Alize and Fin are inseperably fighting side by side. A unique nanotechnology design has been crafted to allow them to support each other directly. As long as the siblings are close they will heal each other, making them able to withstand quite a lot of enemy fire.
