playerprefs problem

I am making a relatively simple game, but i want to know how to save it. I made it using quite a few scripts and i ave two scenes: main menu and the actual game. I want to save the players position and some variables and then be able to have the option to either load them, or make a new file. It would be nice to be able to save up to three or so files. I heard about playerprefs and learned some stuff about it, but i could only find stuff about highscores.

I tried the playerprefs.getint in a script, it didn't work. here's the script i tried it on, before i put in the playerprefs script. It's supposed to respawn an enemy a certain number of times and then stopped. I just wanted, for now, to save how many times it respawned an enemy:

var Beholder : Transform; var targetThing : Transform; var Weapon: Transform; beholder.thing = targetThing; beholder.weapon = Weapon; var deathTimer : int = 0; var maxRespawns : int;

 deathTimer++;

 if(deathTimer == 50 && respawnCount < maxRespawns)
 {
     deathTimer = 0;
     respawnCount++;
     beholder.death = false;
     var newBeholder = Instantiate(Beholder, transform.position, transform.rotation);
 }

}

p.s. I have a pc so i use UniSciTE
