Ok, just tried the Halloween event and good god is it broken. Grinding through the waves takes a fair amount of time and even if you complete most of the side objectives (some are almost impossible and some are literally impossible) you'll barely have enough points at the end to get maybe half the items... For 1 heroine... But here's the real kicker, it's a wave mode where you kill all the zambinos coming towards you, but the buggers are always getting stuck! So after you beat the wave you have to hunt around the map for the straggler that went missing, and this can happen multiple times per round. AND ONE OF THE SIDE QUESTS YOU GET IS COMPLETING THE ROUND IN A CERTAIN TIME. Then there's the times where the zombies seem to disapear of the map entirely... The devs seem to know it's a problem because it seems if the round goes on too long you get an auto win. It's a shame, I was having fun in the first round, this event needs a patch
