Slice & Dice achievement bug

[Tom 狼]

I'm unable to receive Slice & Dice achievement even though I already have Sterling Effort. I'm killing mutants endlessly on Cursed level. Any suggestions?

I have original Metro 2033.

Try killing humans with your knife.

In the front line, I killed all enemies only with a knife and achievement is not unlocked. :/

Then you are looking at trying to do the achievement resetn with config files. There is a steam guide for LL. Just do a backup first.
