I'm pretty new to the game and this next onslaught will be my third one. Having cleared wave 20 on my first and wave 40 on my second one, I would like to try to clear wave 55 this time. While I know that no one has seen the new one yet, what are generalized ideas for a lvl 7 cc base to do to prepare? This last event was my 4th and I cleared tier A mission 9 base defense waves (I took a lot of damage and chickened out on trying further). Thank you.
