I got to the last mission...I'm fighting Kyras...I finally do the damage to complete the objective, but it says to drop Roks on him to beat him...well, I don't have Roks showing up...and I know it costs 500 to do, and I only have 398...and it isn't going up. Am I screwed here and have to do it over, or is there something I'm missing? lol I hope it's something I'm missing...but if I don't get an answer quickly, I'll have to start over anyway. The only global ability on my screen is the turret, which only costs 100, but it's grayed out. And I had 4 or 5 of them - including Roks - before that. I actually used the Roks in the beginning of the fight. Anyone see this before?
