The curator group doesn't mark any game as recommended so it shows useful information about achievements on the store page of the games without influencing the main store page of steam with recommendations + all games sorted to lists based on expected completion times. No point not to follow!:-)


Thanks

The video tries to be a speedrun, while collecting all memories. It is not recorded as a first run, no time wasting "tries" and "explorations".

There are a total of 18 memories in the game. Upon collecting all you will get the All Memories achievement. If you missed one or two on your first walkthrough you need to collect only the missed ones for the achievement, it will unlock as soon as you unlocked the missed achievement.

Each memory also has its own unique achievement.

While there are some unmissable memory achievement, there are also some other stoyline related achievements, these are the following:

The artefact
You have the full power of the artefact now.

Our house
Stop!

The End
Complete the adventure.

There still 2 missable achievement which are not collectibles (memories). Both are very hard to miss, but missable.

Kill the big one
Kill the boss without dying

The "bossfight" is a joke, i can't imagine anyone will die there, you just need to avoid the fix spots where the boss stomping with his/her legs. If you still want to prepare for it you can check this part on the video at 1:56:11

Full violence
Kill all enemies

All enemies are on the main path, you don't need to look for them at the corners. Their aggro range is small, so in some rare cases it is still possible to avoid a fight with a few, so make sure you always kill them at the middle of the areas / on the main path.
