When I played it on IOS, I remember it was a bit.... Unfair, even by X-COM standards for me. Money was harder to get a hold of and bankruptcy was common, aliens have near-perfect accuracy and upgrade to one-hit kill weaponry. That was a long time ago, though. Its also possible for someone to get shot, but the game won't show where the bullet comes from. You just see the hidden movement screen, hear a gunshot, and then a soldier dying.
