I think she had a girl friend that came to visit her and play with her, but said girl also fought with some monsters with a big gun. I think there was a twist that the girl trapped in house was a villain all along and the fighting girl becomes some different entity or something. Please help.";

Makes me think of the TV version of Black Rock Shooter.
There are two worlds, one regular, the other a 3DCG world where cool Vocaloid girls fight each other. The character you're describing reminds me of this girl, since she doesn't leave the house, her other self fights monsters?/the protagonist, and there's a twist or something, and she's actually the villain:
Is this it?"
