At the beggining you probably said: ,, That is going to be impossible.'' .. Yeah, It seems really hard but it's not.

You should: Finish it at least once to know the basics and time.

Few tips and tricks

• At those difficulties it's important to have ammo on bosses and big daddies. Use your wrench on splicers everytime you can

• Try to use environment, It's really helpful. Use explosive barrels and stuff to fight big daddies. 5 or 6 explosive barrels are enough to kill big daddy.

• Always rescue little sisters, after saving 3 little sisters you will receive 'hypnotize' plasmid which you can use against big daddies. Let them fight each other and at the end finish last big daddy.

• Never follow arrow. Always search for loot and then continue in mission. It's really important to have all tonics and items from the map.

• Try to hack everything. You will get some sales or free items. It's really helpful at the beggining.

• Take a photo of EVERYTHING. It will give you some tonics and will teach you how to fight your enemies + it will give you dealing some extra damage.

• Your first upgraded gun will be shotgun. It's really powerful gun which can help you in many situations. Especialy at the beggining.

Important plasmids and tonics

• Must have plasmids: Electrobolt ( to stun and finish enemies ) , Telekinesis ( to throw explosives and get loot from high obsticles ) , Incinerate ( you are going to need this plasmid at Medical Pavilon) , Hypnotize ( really helpful to fight other big daddies )

• Must have tonics:

Combat - Armored Shell ( take less damage from enemies ) , Static Discharge ( when there's too many splicers on you ) , Wrench Jockey ( stack it, wrench attack damage ) , Wrench Lurker

Physical - Bloodlust ( healing from wrench attacks ) , EVE Saver ( using less EVE ) , Medical Expert ( more hp from first aid ) , Natural Camouflage ( to hide from enemies when you are low ) , Sportboost ( Stack it! Very important! It gives you wrench attack speed )

That's the basics. Good luck!
