you'd be right for multi, however i was rocking solo the whole time, after doing cotd solo i had to do this. danger closest made the difference this time round :)

Same here, first solo attempt with danger closest and death and taxes I beat it. I've heard that shotguns, snipers and explosive weapons are all very effective against the boss, and I think it's beneficial for co-op aswell, but so is killing time, if you can guarantee beating the boss at the 3rd stage co-op then that gobblegum is still very useful. There's more than one way to skin a cat. I've seen someone beat it very efficiently solo using just monkeys and the fatal contraption gobblegum

haha dave indeed there is, watching someone do the boss fight, solo, with no perks was quite humbling ;)
