Resident Evil Revelations

Okay episode 4. first collect a lot of ammo. Play through the mission until you reach an anchor door. Go in there the the gun and ammo. Then go to the objective. You will have to fight Rachel. Use lots of bombs on her. Then just shoot at her with upgraded weapons. I defeated her with parker in the cafetería. But if you don't want to miss out on a achievement kill her before the cafetería. You get 4 chances. Once she is dead the rest is easy. Episode 5 When you reach the invisible enemies use your shotgun and assault rifle. It might take you a few tries. Episode 6. To get out of the flooded room you need to find and use the 2 pipes to open a vent. Once out of there climb the ladder than kill the enemy the a bomb. Next try to avoid the enemies. Save your bullets, you will need them. Once you reach the open room, parker will lead you to a lift. Get your sniper ready the powerful one. Use it to scare away the boss. Once on the deck you will face it again. Use the sniper to shoot it in the little heads. Remember to dodge attacks. Also shoot the fuel when it's close enough. Parrker finished it off for me luckily. Just focas on the heads and you will be fine. I hope this helped.
