This page lists all the secrets hidden in Mega Man Armageddon.
- Beating the Robot Master only using the Mega Buster allows the player to play as the Robot Master. The only difference is that the character will only have one weapon to use. It can be only done with the Robot Masters from Phase 1 and with the Robot Masters from before Wily's Facility.
- At the end of Wily's Stage 4 before the boss, you can find a Yashichi hidden inside a Met, if you defeat the Met, you will gain the Yashichi. It will heal you and fill your weapons' energy.
- If the player goes to the right door instead of the left door on Dr. Wily's Robot Manufacturing Plant, Floor 4 (where the player fights the Copy Robot), the player will instead fight Bond Man, an unused robot master from the first Mega Man game. Defeating him doesn't gives a new weapon for Mega Man, however.
