Online achievements aren't very hard just take a little time. You will notice a difference on this difficulty, as you now will not be able to take as many hits before dying and the enemy AI is more accurate. You could have skiped the easy playthrough and gone straight for this but it might have made things more difficult for you depending on your skill. Now that you have all the story based, collectible, and miscellaneous achievements out of the way, it's time to do a playthrough on Sniper Elite difficulty. You can check your overall stats in the 'Extras Menu', that way you know how far you have to go to unlock an achievement. Since you started the game on easy it shouldn't take long with easy enemies and chapter select. Now that you have finished your first playthrough and have a feel for the game, go back and get any achievements and/or collectibles you may have missed.
Step Two - Collectibles/ Miscellaneous Achievements Use this playthrough to enjoy and get a feel for the game. It doesn't matter if you miss collectibles and achievements on your first run as chapter select allows you to go back and clean up. It's a good opportunity to get to know the bullet drop over different distances and makes it a hell of a lot easier to get the collectibles and miscellaneous achievements. I would suggest doing your first playthrough on Cadet difficulty just to get the hang of things. Does difficulty affect achievements?: Yes Do cheat codes disable achievements?: None Number of missable achievements: NoneĀ ( Chapter Select) Minimum number of playthroughs needed: 1 ( 2 is Recomended) Approximate amount of time to 1000 : 14-16 hours
