R7 Gun Battle Robots are robots deployed by G.U.N., appearing as common enemies in Shadow the Hedgehog. They are much stronger than beetles and soldiers and they serve as one of G.U.N's most powerful robots throughout the game.
Those G.U.N troops are humanoid-like robots made from a very solid iron. They have a good resistance from damage as an ability comes from their build-in matterial, however they are not as strong a the Big Foot. They usually armed with heavy weapons such as RPG/rifle/bazooka and many others. They take four hits by Homing Attack, two hits from a medium Machine Gun, one hit from the Shadow Rifle and other most powerful weapons in Shadow the Hedgehog. When they destroyed they will leave the weapons they hold.
