Just something I thought I'd put up as an achievement-like challenge for anyone to do. The challenge is simply this:
Kill any Pinger on Supersolider difficulty using no other gun besides the Nova pistol. The Nova may be equipped with any attachments, but no other form of damage may be inflicted upon the Pinger except with said gun.
In order to prove all requirements are followed, put up a video of you performing the feat showing from start to finish your battle with the Pinger. Videos can be the crappiest quality as long as they show you started on Supersolider and used only the Nova pistol to kill the Pinger. No deadline and no prize except the rest of gamesas knowing you did it, and anyone who tries a hearty good luck to you all.

Nice idea I'll give it a try. A pinger is one of those big tripod robots right?

Yup the ones from Domination Challenges...

Anyone managed to complete it yet?
The reason I put this up is that I tried to do just that. I worked away at it for a few hours but then got sloppy and it destroyed me. Thought I'd see if anyone else can accomplish it.

I will give it a go when I go through this on Supersoldier, but right now I'm waiting for black friday for a bigger TV so I'm holding off from my Crysis 2 playthrough until then

You mean you haven't played the campaign yet?
