Get a shooter, and play the game on the easiest mode with the controller upside down, and see how long you live.

Every 30 seconds: 1pt

Every 1 minute: 5pts

Every 2 minutes: 10pts

And then it keeps doubling with each thing (E.G.: Every 4min = 20pts, Every 8min = 40pts)

For example, if you lived 5 minutes, you'd get 55 points.

Good luck!

Edit: NO COVER AND/OR CAMPING ALLOWED!!!!!!!!!!!!!!!!!

Haha, that's like when I beat my mate at Mario Kart 8 with the controller upside down behind my back. He though he was so good until then =P

I am so bad at shooters I would not even have to hold to controller upside down to die in less than a minute
:/ True

I'd be a lot easier to get the hang of it upsidedown, but that'd be fine. 

The point is that you don't live long, so you keep trying until you master it!

I've played a few but really the only I could get into was TF2, it really isn't my type of genre

I am not able to use any of the buttons or analog sticks if I hold it upside down.
Which axis are you talking about^^

And that reminded me of this video:

This is the best way I can explain it:

The only shooters I really like are Third Person. Uncharted and Tom Clancy's for example.
