Complete the game on Hard difficulty without using a Vita-Chamber
For some reaosn people thing that this achievement is really hard, but the reality is that its is really really easy. So below I am going to give you some tips on how to get this achievement really really easyily without much effort. I have yet to get but I am almost done with only 3 hours of play tottal.
NOTE: In order to obtain this achievement you must go to options in the game's menue and turn ON "Disable Vita-Chambers." If you do not do this and die you will spawn in a vita-chamber and HAVE to start the game all over again. Even if you did have a previous save without the death. If you sapwn in a chamber the entire save is messed up and you will have to start over.
Tips
1. Save everytime you accomplish a new objective or in the middle of a fight, and before all bosses.
2. Skip as many splicers as possible. Only kill objective completing splicers, to make things go faster.
3. Save as much ammo as you can and use the wrench as much as you can and wrench jockey tonics to keep up the strength.
4. Don't wait to use first-aid. Use it right after fights even when you still have half-health left. Waiting to use health during battle is a bad idea becaue you might forget you have half health and instead you think you have full health and die.
5. Check all crates, trash cans, and dead splicers bodies for extra first-aid and eve items when you find your-self out of both and in a tight spot.
Defeating ATLAS
This might be tuff for some people who havn't even beaten the game on hard so please read carefully.
When you get to Atlas, the finall boss of the game, you need to make sure you have full ammo for the crossbow (including the regular,armor piercing, and anti-personnal rounds) and full eve and full first-aid packs. Anything else is not needed for this fight. When you first start out you need to run up to him and grab ADAM from him for the battle to start. So do that. When he comes down, he will start out as a fire element. So switch to your Blizzard plasmid and shoot at him to free him and shot a regular crossbow shot at him. Repeat this untill he goes back on his restraining table. Go grab more ADAM from him and he will come back down as the ice element. So hit him with your inferno plasmid and then shoot at him with your fire crossbow. Repat this untill he goes back up. Go grab more ADAM and he will come back down for a third and final time. He will be a multi-element so any plasmid and crowssbow shots will work. This time when he is down you will also have a couple of splicers who will come down and try to attack you. Don' worry about them becasue the AI on these are really bad and will rarely hit you, just focus on Atlas. Keep shooting your crossbows and he will eventually go down.
If for some reason you do happen to die please be sure that you had a previous save somewhere close by the same part. If you didn't I suggest turning off your xbox and loading the auto-save.
