Cho Ren Sha 68K[a] is a 1995 vertically scrolling dōjin shoot 'em up video game developed and originally published by Koichi "Famibe No Yosshin" Yoshida at Comiket for the X68000.

Cho Ren Sha 68K was first made for the X68000 due to its popularity in the dōjin and freeware development scenes, being influenced by several shoot 'em up games in arcades that also played part with its design process.

The title was met with mostly positive reception from reviewers for its presentation, graphics, music and gameplay; criticism was geared towards various design choices but has since gained a cult following, serving as an influence for ZeroRanger (2018).

Cho Ren Sha 68K is a vertically scrolling shoot 'em up game in which players take control of a space fighter craft to fight against enemies and bosses on a ring station.

[1][2][3][7] Yoshida stated on his personal website detailing development of the project that it was influenced by several shoot 'em up games in arcades such as Batsugun, Tatsujin Ō and Battle Garegga, among others that also played part with its design process.

[7] When balancing the player's firepower, the player shot appears four times more powerful that the initial state, however the damage delivered is "only 1.375 times greater" as quadrupling damage output would break the game if it matched the appearance of the maxed power shot, with Yoshida stating he learned deliberate fine-tuning from Toaplan titles.

[7] Yoshida also decided to adjust firing accuracy depending on circumstances and cited various titles like Flying Shark, Parodious Da!, and V・V as examples where enemies had low-accuracy aiming.

[7][8] Kashiwagi had previously written original songs for the X68000 during his high school years before meeting Yoshida via a networking system in Japan and took the task of creating music for the project.

[19] Likewise, Sven Ruthner of Retro Gamer CD gave positive remarks to the graphics, Kashiwagi's music, sound design and gameplay mechanics.

[26] David Borrachero and Zed of Spanish magazine RetroManiac noted its visuals as reminiscent of early Toaplan titles, music, frenetism and difficulty level.

[29] Maciej Miszczyk of Hardcore Gaming 101 praised its level design, music and gameplay, stating that it has a place among classics of shoot 'em up genre.

[33][34] Rival Megagun creator Justin Rempel claimed in a 2018 interview with Japanese website 4Gamer.net that Cho Ren Sha 68K is the shooting game he admires the most.
