I find Nemesis best and WORST since it annoys you from the start unlike other mosnters.
If you didn't play RE:Remake, then here's a lil info about Lisa Trevor:
Who's Lisa Trevor? Well, she (I THINK) is the wife of the person who designed Spencer Mansion but the owner of that mansion invited Trevor's family (except her Lisa's husband) to the mansion but disappeared... No one knows why until RE:Remake.
Anywayz, Lisa Trevor is sort a like Nemesis in RE:Remake unlesss you don't know the easier way of beating her. I am not going to tell you. I got it from RE strategy guide
So which one?
