You know what would be cool. No you don't, but I'm going to tell you.
It would be really cool if instead of the kamikazi being a console command if it were a special weapon. Should probably only cost 1 credit. If it were a special weapon it would probably also make sense if it weren't on a timer, but more like a deadman switch. (pun intended) Or maybe have a switch that's triggered from the primary fire of the knife spot.
You know what would be even cooler than that. Once again I have a feeling that you don't, but I'm going to tell you anyway.
It would be really cool if you could combine the blast armor and the kamikazi with trigger and not die.
Ok. I'm done. Just a though.
