XCOM: One Does Not Simply "Shoot" a Cryssalid...

[Surrealistik]

Really? They are, bar none, the best at live capturing aliens. For this alone, I prefer them over Heavy. Heck, I'd run 3x Assault, 2x Sniper, and Support before I'd run 3x Heavy, 2x Sniper, and Support.

I do take Assault along when I'm specifically looking to capture aliens, but my default, general purpose wrecking crew remains the latter as it strikes the best balance between killing efficiency and safety in my experience.

3x Assault though is kind of silly; you need cover destruction for Snipers to work optimally.
