History:
Built by Horis B. Gorge in May 23, 1890 after the first encounter's of Rebel tanks in a battle of the western trenches during a move to capture the rebel capital to have there advance smashed and destroyed by the armaments, This rifle proved very valuable and effective to the tanks coming with three types of shells: Explosive, Armor piercing and insanitary. It saw limited use against foot solders advancement's in the trenches but also like the tanks were used effectively against aircraft and fortified positions that needed to be dug up. after the collapse of the government the company was dissolved as well as a Xeno running off with all there money, weapons schematics and shares leaving them bank robbed and out of business in the year 1899, the rifle is still is use but made by other company as copy's holding that company's name not the Horis company's name, If you find a Horis weapon like this one it is very valuable and considered a collectors peace.
This rifle is still used to this day by military factions as well as mercenary's for its devastating power.
