This order is some Dr Evil shit.
[Joel] It's time we teach those players a lesson. We're going to hold their weekly medals to ransom unless they kill... [dramatic pause] ...2 billion bugs!
[Arrowhead intern] Erm... Mr. Joel, Sir? Don't you think we should maybe ask for more? The players routinely kill a billion bugs every day before the Americans have even got out of bed.
I'd love an order that's just kill as many as you can. 10 medals per billion. Watch the playerbase go nuts.
I also did my first base defence mission, on suicide difficulty. I don't know what bots are like but bugs were ridiculously easy.
I'd say we did it with no deaths but someone managed to kill themselves 1 second into the mission, presumably by landing on something explosive.
We never retreated, and only lost 2 gates to bile titans (but re-took the ground). By the end I had about 8 EATs sitting around me with nothing to shoot them at.
Eruptor+Arc is a great combination for bugs. The Eruptor is perfect for stopping/popping spewers (1 shot for yellows, 2 for greens).
You need EATs or teammates for titans or charger spam but everyone and their dog seems to be packing a quasar cannon these days, so I can usually let them deal with heavies.
