Lets talk about Gunvalkyrie Xbox

Eenter a world filled with alien hostility, heavy artillery, and cutting-edge genetic technology. The ultimate mission: exterminate an aggressive alien species. The story opens in a world much like our own, in a time much like the 19th century. A lone scientist has made a string of incredible breakthroughs, yet the technology develops far beyond his intentions - and his control. The result is a world of chaos, biological anomalies, and unsanctioned weaponry. With the government's assistance, the scientist is able to form "Gun Valkyrie," an organization whose mission is to protect new technology and police its use. When the scientist suddenly disappears and a host of nightmarish creatures appear, Gun Valkyrie is called upon to find the scientist, eradicate the mysterious creatures, and return order to the world - by force.
