Um, Creeper?<br/><br/>Sarah is not with the main group, and she's not in LOS of any mutants ATM.<br/><br/>When mutants do appear near her, they will be over twenty meters away.<br/><br/>I suggest that Dellila join one of the squads, and fire at the mutants in the east battle.<br/><br/>If Sarah had seen Delila following her, she'd have warned her to stay back, as Sarah will be using the Walker's speed to stay ahead of any mutants following her, something she can't do with Delila at her Setinel's heel.<br/><br/>Oh. And good shot.
