Bullet-Proof Software (株式会社ビーピーエス Kabushikigaisha Bī Pī Esu) was a Japanese game developer founded by Dutch developer Henk B. Rogers. The company is probably best known for bringing the Tetris series to the United States.
In 1996, Rogers created Blue Planet Software, which acquired BPS. In March 2003, BPS was dissolved.
Goblin Sound was hired to compose music for BPS's in-house games. They used a sound driver by Kazuya Takahashi.
