Whilst playing, I've learnt that you can turn the power on and off. No big issue, except when you have Mule Kick and turn the power off, you lose your third weapon. When you turn it back on, you get it back. Nothing big happening, except when you buy a weapon it takes up another slot.

Eg. I have Mule Kick with 3 weapons - Ark-7, Spas-12, M1927. I turn the power off and back on, which got my M1927 back. Then once that was done I decided I wanted to replace my M1927. So I go to the equivalent of the box, buy a weapon (oh, MG08/15) and I swap it out. Or I think so. When I scroll through my weapons, I find that my M1927 is still there. Which means I have 4 weapons.

Upon further insight, this can be done multiple times over. So it could go to 5, 6 weapons. More. And if you happen to lose Mule Kick when you have, say, 5 weapons, you keep 4.

As useful as this is, it'd be pretty easy to get buffed with this. And then it'd get a bit unfair if others were playing.

...is it too late to attempt?
