Aliens received a NES port in 1988 by Introware on behalf of Activison, which Activision published itself worldwide.


The gameplay is the same as on the computer versions, except it is the Commodore 64 version and it was programmed using an Acorn Electron. The soundtrack is converted by Eeli Ikäheimo using the Introware C64 Conversion Sound System. The background's antics were changed to fit Nintendo's censorship guidelines.
