Fail? Go forget yourself.
Suggestions:Bullets should ricochet off if they hit the shield at a very small angle.Also it should get damaged if powerful projectiles hit it (If the projectile makes 60 or more damage, the shield gets damaged).Don´t know if its possible, but eventually that very powerful projectiles pierce it (Projectile makes more than 120 damage or something -> pierce and eventually let the player drop the shield).
Does for me.
