Your idea for a Mega Man Legends 3 easter egg could make it into the game.
The Mega Man Legends series has featured many different easter eggs to keep players entertained when taking a break from robot blasting. Capcom wants a similar number of easter eggs to be included in Mega Man Legends 3, and you can have an impact due to the unique nature of the game's development.
Capcom has started a community "dev room" to get fans involved with the design of various aspects of Legends 3, such as the game's heroine and a mecha. The latest campaign is all about secret easter eggs.
As an example of what Capcom is looking for, the original Mega Man Legends had cans lying in the street that the player could kick into a store for cash, but doing so would annoy the shopkeeper. Another easter egg featured the ability for Mega Man to keep the money from a bank robbery, but this act would turn him completely black. Capcom wants some new ideas for these types of secrets it could include in Legends 3.
To get involved, go to the Mega Man Legends 3 dev room forums and follow the instructions here. The easter eggs must follow the guildlines of four specific abilities - kick, jump, grab object, and throw object - but other than that fans are free to come up with whatever unique actions they can think of.
Some current suggestions include skipping rocks across water and a cameo by Phoenix Wright. Can you think of anything better?
