Strangely, both Cybernoid and Northstar are also featured on Gremlin's Space Ace collection. The five other five games include the excellent Exolon, Dominic Robinson's horizontally-scrolling shoot-'em-up Zynaps and the third MASK game - Venom Strikes Back. While fairly expensive, and with some rather mediocre games as padding, the good games more than make up for this.
Venom Strikes Back 53/91%
