How do I kill the two horses help me please?

Start shooting one of them.Then when it goes crazy wait till the screen blurs dodge. The when the target circle turns red shoot to stun it.Then use your grapple to take the shield. Then shoot again till it goes crazy but stay near the shield .And this time it wont charge at you it will try to freeze you. So pick up the shield and aim it towards the horse. It will freeze start to shoot it and it will loose health.Keep doing that to both and they will break.(if you freeze start hitting the analog stick left and right quickly to break free.) Good luck!

Codes are naughty :D - but anyway when the use that annoying
"turn-you-into-stone-thingy ray" you let go of L1 which stops targeting them. If you do that while they're zapping you thay'll miss. After that keep shooting them and build their rage up until they charge at you. When they charge at you and it goes into slow-motion dodge it and accuratly shoot them in that special slow-mo-thing and then they go all dizzy. Then grapple onto their shiels and they'll drop off. If you can-then try doing it to the other one. If not then do it later. When the stop being all dizzy then you can build their rage up by shooting them and when they zap you with their "turn-you-into-stone-thingy ray" make sure you're next to their shield which should be on the floor because you just pulled it of. Then press (triangle) and you'll pick up their shield. Their "turn-you-into-stone-thingy ray" will then be reflected back at them and they'll then turn into stone. Then you shoot them while they're stone and their heath goes down really quickyly and easily. When their health goes down to the very bottom they'll shatter and that'll be the end of them... ^_^ lovely.

Hope that helped =D
