I've been playing the level 6th of shadowgun like 30 times on a row and is impossible for me to kill the predator looking with a rifle, can someone with experience on this game could please help me out? I emptied my Armour the whole bullets of the rifle, then with the shotgun and whit the missiles and all he did was lean foward on pain or whatever but he never die!! It is a bug on the game or is just me? Thanks in advance
