Muramasa: The Demon Blade was first released in 2009 for the Nintendo Wii and was later ported to the PlayStation Vita with a new name, Muramasa Rebirth. It was developed by Vanilaware and published by different companies for both versions and different regions.
The game is set during the Edo period of Japan where the current shogun, Tokugawa Tsunayoshi, is causing problems with the ownership of the legendary Demon Blades; the darkness that provides the Demon Blades power has reached through the weapons and has begun to summon demons while attracting the attention of Ancient Gods.
Muramasa follows two main characters on their own stories which intertwine as the game progresses; the pair must deal with the power of the Demon Blades which puts them in danger of possession, death and worse.
Four other stories called “Genroku Legends” are also featured in the game and are inspired by traditional Japanese Folklore; there are different main characters for each story where they fight to complete their own missions.
It's a 2D side-scrolling ARPG where the player needs to fight through each level to complete it; despite the style of the game, it's possible to avoid some fights with enemies by not coming into their range on the screen.
The player is able to perform combos by attacking in rapid succession or combining the attack button with directional keys. Various items can be used during combat to provide the player with an edge over the enemy; healing items can also be accessed and used during or outside battles.
RPG elements from the game come from the experience points system where the player can select which aspect to level up in accordance to their playstyle; each type of weapons has unique stats and can be used to block incoming enemy attacks. A total of 108 different blades can be forged in-game through the skill tree which allows players to create a weapon that suits them.
