Jump on the bubbles that appear each time he stops to do something (only a few seconds).
It can be a challenge, might be easier with a friend or two.
You ace the collector
The collector in the bunker.
Lbp1: The Collector Lbp2: Negativitron
The best technique is to go through the level a few times to perfect your knowledge of the order and patterns of attacks he uses. Once you think you've gotten it down good. Try to ace it.
Most likely it is not going to be available for a limited time
You get 100% collector trophy (Silver but should be gold)
Walmart.com has the collector's edition available for preorder along with the regular addition with The Great Gonzo bonus
you have to defeat team galatic
To ace any level, you must complete it without dying. I would suggest looking up a walkthrough on IGN.
the last one "The Collector" not to bo confused with "Collectors lair" that is my opinion. the hardest level is "The Bunker" in the wilderness theme
you have to doge the bullets by jumping the to either throw a cake at the bubble when it comes or jump on and hit it
Theres a times 4 area in the first level of the collector. It's located near the end of the level where an elevator is. Good luck! my psn User:RoxasFanJordan
