During their Otakon 2014 panel earlier today, MangaGamer announced their plans to adapt Chou Dengeki Stryker for the Steam platform at an unspecified date.
The only difference between the original Chou Dengeki game and this Steam version is the omission of H-scenes, therefore they will be offering everyone who already owns Chou Dengeki Stryker a complementary Steam code to add to your library.
The hard-copy version of Chou Dengeki Stryker on the other hand is still set for release in September, and will of course be the original, 18+ edition of the game. They are also hinting at a possible limited edition that might be confirmed at a later date.
