Got to tile L51. The Reavers or what the name of those Mecha Walkers, are quite nasty but not unbeatable if you have lot of Armor Pen. TD.
Its worse if the AI spawns one or two while your tanks are hammering on the enemy Heavy fckn Tank commander.
The problem I see so far is if you want the extra copy, you´ll need to hope for good luck on those turkey wraps or wtf are they. Not even worth throwing your cores at it in the exchange shop due to the random, low value.

Kinda dissapointed that there is not 5* tank included in the event shop. Just a random 5* emblem, and I wont risk that one to turn out to be a shit like rotation or something. Guess just keep on hoarding those Cores for Xmass.
