Power suit plasma cannon problem

[Grasshunter]

I have installed the plasma cannon to my power glove and installed an elite battery but it wont fire.what key do i press to fire the cannon? the mouse buttons don't work.

I am also having the same problem with the blink/warp attachment.

You have to 'select' which attachment on the arm you want to use. The Default is none, so you have to shift right click to cycle through them (I think). Once you have one selected you should be able to just right click to utilize it.

Cheers.
