Thoughts on The Evil Within

[Kreekakon]

One thing I do not get at all is: why have they implemented a melee damage upgrade if you can't kill the enemies with melees?

Judging from the wording of the game's upgrade system, melee damage does extremely small amounts of damage, but damage nonetheless. If an enemy has been already damaged low enough, or if the player is persistent enough I think melee attacks CAN kill an enemy...although it is highly impractical.
