Other games like Aliens: Dark Descent?

I recently started playing Aliens: Dark Descent and I'm really enjoying it. It has a strong narrative and environmental storytelling with real-time gameplay and combat. Are there other games like this I should check out? I've also played Dawn of War 2, which is very similar (squad-based, real-time gameplay). Most of the ones I've seen recommended are turn-based, which I'm not interested in.
