Ive finally played Amensia. Heres my Review (plus Penumbra comparisons)

[Brennenburg]

I agree with 9 out of 10 and I also agree on how you said that once you hide in a cupboard or whatever the monster just delete off the level once they walk away from you.

Wouldn't it be possible to make the monsters not vanishing with the map editor for a tougher difficulty? Some custom stories use monsters that permanently patrol. I don't know the editor: Would that be a lot of work or would it just mean to delete one "vanish monster!"-line of script per monster?

I have no clue I'm a total novice when it come to the HLP2 editor. The only editors I know with experience are the CryEngine2 Sandbox Editor and the CryEngine3 Sandbox Editor.
