Here's something for those who are bored with "nothing to do."
I've had more than a few friends show me different challanges they have devised to test a certain skill in the game. This one tests several, most importantly the ability to manage multiple targets in a fight and pick out the right one.
The challenge is to reproduce a screenshot similar to This One, in the same location with the same four (no points for only three, or less) guest stars.
(Take note of the depth, this is in the Arcade Jelly Palace, not the watered down mission one.)
Note: For those who know how to do this, don't post the solution for those who aren't sure. Part of the challenge is figuring it out. If you see how, but can't be bothered to DO the challenge, give yourself a pat on the back for being clever, but don't spoil it for those who don't get it and want to try, please.
I rise to you the Trojan Challenge.
