Serial Killer Trophy
Kill 40 enemiesPOTENTIALLY MISSABLE
Unless you are consciously avoiding killing monsters, you will get this trophy shortly before entering the Mausoleum.
Although it is technically possible that you could miss this trophy, the game balances the amount of ammunition at your disposal quite well so it is possible to even kill all the enemies of the game (a little over 70 enemies). In this way and so that you do not have problems in obtaining this trophy, simply try to eliminate all the enemies you meet until you get it, considering the recommended strategies to deal with each type of them mentioned in the Additional Resources Suplementary Guide.
