Recently I come back to play through the old mod version of Black Mesa, now I want to say something for the details in the mod. I think these are better than the steam version we have now, I hope that sometime in the future we can see them in the game again.
1.The blood stained weapons.
Begin with the satchels and the tripmines, I made pictures to show the difference.
In the mod version, when you throw out a blood-stained satchel, you will get a new clean one, and you can see the former stained one left on the ground.
But in the Steam version, you will throw out a new one, the stained one is still in you hand.
The same as the tripmines, like below.

This detail is very good I think, hope devs can add it back to the steam version later.
Add two gif to show them clearer
