I like to use explosives to soften 'em up and THEN shoot them in the head.

Besides, I am always carrying around 50 or more frag grenades anyhow. Gotta use 'em for something. Nothing better than crippling a Primus or an Overlord and then headshotting him. Very satisfying.

I could see how that would be a great tactic. I like my victims unaware of their deaths. I'm gracious like that. They feel nothing as their heads pop off.

If a mini nuke doesn't kill something, how will a critical make much of a difference. Maybe if we had a Rad-Godzilla in our game, but no. I haven't even used my Fatman. Maybe I will shoot a few nukes for kicks, but what enemy would require one to kill?

Something of the large, irradiated variety....or loads of little guys,
