ALF[3] (アルフ) is an action-adventure video game developed by Nexa and released by Sega for the Master System in 1989.

The game was a side project for Kevin Seghetti, who at the time was under the employment for Nexa, then integrated with Spectrum Holobyte, who in turn changed their name to Sphere.

Although Seghetti was not a fan of the ALF TV Show, he worked heavily on the game's engine.

In the later stages of development, ALF was lacking audio and the producer John Sauer did not have adequate game design experience.

With only a maximum budget of $200, Sauer managed to find Randy Roseberry to compose the music and sound.
