I really want to enjoy this game but I hate Nemesis. He chases you, you run to a door, but then he reappears again and he kills you way too easily. How do I get him off of my back for awhile?

Where are you in the game?

Nemesis can be frustrating at times, this is obvious but that's why you need to be fast and quick thinking.

I don't remember him continuously chasing me though. When he does appear I just run like crazy to the next door.

just have to master dodging. and there's a trick on how to run around him without being grabbed. was it his left side? or right? dont remember... anyway you can hide in a save room, but he still waits outside.

ive never had a problem with nemisis

just dodge and stab when your low on ammo

You can lose him at the save point ONLY if you are quick enough to get in before he comes. Increase your volume and listen carefully to the sound.

Sound of door opening = that's him in the area.
Sound of heavy footsteps = he is walking (but chances are, he didn't see you yet).
Sound of a roar = he sees you.
Sound of theme playing = he is rushing toward you.
Sound of a game over theme = too late, you're dead.

If you can rush into a save room before the sound of door opening behind you, the chances are, he could go pass the save point and toward the other side. Wait a few minutes, get out of the save point and go elsewhere but not at the immediate area.

Important - always listen to the sound of the door opening or a roar. He roars, you run. That's the rule.

Once you unlock the Mercenaries mini-game, and earn enough points to buy yourself an infinite ammo rocket launcher, that's an excellent way to keep him off your ass for a good long while.
But that really doesn't help first-timers now, does it?
*smacks self in face*

during my first play-thru I had to restart

....can't you just beat the *bleep* out of him?
