Samurai Shodown 2 (サムライスピリッツ! 2 / 1999

Samurai Shodown 2! (サムライスピリッツ! 2 Samurai Spirits! 2?) is a game released by SNK in 1999 for the Neo Geo Pocket Color.
It was designed as a conversion from Samurai Shodown 64: Warriors Rage, and almost all of its story events, endings and cutscenes are derived from its arcade cousin. It turned out to be a surprisingly robust rendition, with almost all characters from SS64: Warriors Rage being included (the sole exception being Hanma Yagyu). It also re-added two series favorites who were not in the arcade, Charlotte Christine de Colde and Jubei Yagyu.
The game is avaible as a pre-purchase bonus for the Nintendo Switch version of the new Samurai Shodown.[1] It's the first time in 20 years that a title from the Neo Geo Pocket Color game library has been available on another console.

An exclusive and limited physical version has been released by Pix'n Love Games as part of the Samurai Shodown Switch - Shockbox Gold Edition.[2]
Gameplay
SS!2, as it is abbreviated, kept very true to its arcade origins, retaining most of the gameplay elements of its source game, albeit modified to work within a 2D setting. SNK had, by this time, had more time to grow comfortable with its handheld hardware, so the game is considerably more refined than the original Samurai Shodown!.

The Slash and Bust modes for each character were retained, with all of the moves from the arcade kept intact (except for Yuga, who had a third form in the arcade, which was mostly excised). This was particularly impressive, given the original's sizable movelist, and the fact that the NGPC only had two buttons instead of four. The original "CD combo," first introduced in Samurai Shodown IV, was also retained, but simplified and streamlined from its origins.

Being a game on a handheld platform, versus play was not a primary focus, so SNK added in a "Collection" mode, to extend the game's longevity. This came in the form of virtual cards, which could be traded with other people who owned the game, by linking up systems. There were eight per character (four for Slash, four for Bust). These cards served two purposes:

Each card contained a different piece of art, drawn in the game's cartoonish art style.
Each card carried a bonus that could be equipped on your character, and there were four types.
Power Up - Increased the damage done by the player's attacks.
Defense Up - Decreased the damage taken when the player is hit.
Special Move - Enabled the player to do a special move which was not otherwise available.
Power Up Special - Made a particular existing special move do more damage, usually accompanied by additional animations.
