About achievements..

1. Are there any missable achievements I should know of before going in?
2. Are there any achievements related to dlc or such?

Thanks in advance.

1.
- Gather all secrets in one run.
- Upgrade everything - require playing New Game+
- Heroic mode(max difficulty and dying means restarting the whole level).
In theory you'll need at least three runs for all achievements, and then maybe some farming like killing with environmental damage only.
2. No, DLCs are only for sword models.

There are other achivements that you may need another playthrough to complete (Alice in Shadowland and cookie monster, and other grindy achivements) but the good thing is that you can load a chapter in the main menu if you've unlocked it. And for a lot of these achivements you can just quicksave and quickload to grind. So you won't really be missing anything that you may regret later, as you can just come back to a certain level or certain grind spots and just complete the achivements.

If you find the game to be hard, I would suggest starting a normal/hard (or hell, casual) playthrough, complete it, then do NG+ in Insane (as you will have all the weapons and upgrades from the other playthrough).

Keep in mind that the achivements that "depend" on a certain difficult (Do this on XXXX difficulty) can all be unlocked if you complete the achivement in the highest difficulty (so if you complete an achivement in Insane, the Casual, Normal and Hard variants of that achivement will be unlocked aswell).

yeah, thank you.

actually, the "Cookie Monster" achievement can technically be exploited and unlocked in only a few minutes!!!!

the way to do this (providing you're not playing on Heroic), is to approach a fortune cookie and immediately save your game before picking it up. So that way, you can keep reloading the game over and over until the achievement unlocks.

yeah it's a bit of a cheat, but at the same time, it's sometimes best to get the collectible-based trophies out of the way first.

Hello. Could someone answer this question of mine. I would like to know if when I have to play the game in heroic mode I will unlock the achievement of killing the Warlord and other boss in insane mode or will I have to replay him in insane mode?
