I like the idea of the 2 walker tanks with some sort of mechanic where they have to hurt each other. You kind of lost me in their with the power core having to be taken and returned and whatnot. The concept seems nice but confusing in the details, what do the other players do while the 1 person has the core? Nice idea though Edit: just saw where you said everyone else kills adds and stuff during the phases, not a huge fan of that but who knows !
