Went into the negatives with my energy then went to use an energy cube but it wouldn't allow me to use it. Pain I have to wait to recharge to 0 just to use it. Just wondering if this should happen.

The bigger issue is why did the game allow you to go negative. Please use the app report link and give as accurate information as you can. There are two issues at work that Webguydan needs to troubleshoot.

Thank you.

How did you get negtive energey?

During the mission "Slowing the Prejor Advance", there is potential for energy discharge (minor energy loss), so if the player used his last 20 energy and triggers the "discharge", then the player goes into negative energy.

I am probably misremembering, but there might be another mission like that also.

Stryll infection maybe, not sure but what happens when you hit it with less then 50 Energy?

Ya i did The Krionite Vortex

Yeah, that is the one I was trying to remember^

And Investigate a Black Hole
