Biohazard EXTREME
No offense, but Linda was more of a burden than Ashley. I'm sorry, but it's true.
What do you expect? She was shot in the ankle. You can't expect her to be a ton of help after that. Besides, at least she has an awesome personality, unlike Ashley.
Although, she is still more useful then Ashley, because you can use her to access the "Shouldering glitch" that makes you invincible for about 3 seconds. Makes it easy to get past the part with the sniper.
