Mega Man 5: Blues' Trap!? is an FC action game released by Capcom on December 4, 1992, the fifth entry in the original Mega Man series. It retains the two-castle system from the prior game, featuring 8 Robot Master stages, 4 Blues Castle stages, and 4 Wily Castle stages for a total of 16 levels.
Set two months after the fourth battle with Dr. Wily, the story follows Mega Man, who is curious about the mysterious Blues. One day, Blues leads 8 robots in a global rebellion, kidnaps Dr. Light, and leaves behind a yellow scarf. Mega Man sets out on a new adventure to uncover Blues' true identity.
The game introduces several system improvements:
- Mega Buster: Faster charge time and wider range, but taking damage during charging resets the charge.
- Special Weapons: Deal base damage even to non-weakness bosses.
- Rush Functions: Spring Rush has a higher jump, Jet Rush works underwater, and Submarine Rush is removed.
- Beat System: Collect 8 letter circuit boards ("R","O","C","K","M","A","N","5") across the 8 Robot Master stages to unlock the new support robot Beat.
- M-Tank: Fully refills health and weapon energy at once, but only one can be carried.
- Weapon Switch Interface: Special weapon names are now the boss's English initial plus the move name.
- 8 Boss Rematches: Exit teleporters are removed; players leave the stage automatically after defeating all 8 rematched bosses.
In 1999, the game was ported to PlayStation, adding a Navi Mode, rearranged soundtrack, and a richer gameplay experience.
