Whoever suggested Lappi for annihilation, that worked out the best. She held back most enemies, including the big guys, and I could focus on the drones by redeploying whenever one would sneak by. That's two maps done in a single day!
That brings me to something else though. The rewards I got finally tipped me over 180 gold certs... sooo who to take? Kal is up now and I like her, but is there anyone else worth waiting for?
