The HQ of the Earth's defense thought everything was safe after the first victory in X-Out. But it appears that enemy activity is growing and once again you are called into action although this time you do not need to be alone, someone else brave enough can join you. Thousands of hostile organic enemies threaten the safety of your planet again, and they must be destroyed over the course of six (huge) levels. There are power-ups available, but the game is less centered around these than some are. Z-Out is a classic R-Type clone, that features same weapons like the force device, the extra weapons, the drones, the charge beam! The six levels contain hundreds of varied aliens and host of scenic targets and gun emplacements. You'll also encounter two huge guardians per level and a series of moving pillars which must be avoided. You can tell that the Advantec Software team has played their share of Japanese-style shooters. There's no trace of the many minor flaws usually found in western-crafted shooters.
The quality of the graphics on the ST (and the Amiga) varies a lot throughout the game. Levels one and three look very good, although parts of levels two and four look a bit out designer's imagination. Levels five and six, however, are absolutely astonishing (designed by a different artist). The ST version uses different colors than the Amiga OCS and, in most cases, are less in number. But both versions look good. The main difference between the two versions is on the sound.
The sound on Amiga uses catchy tunes and crisp sampled SFX that suit the game perfectly well, while the ST has only chip-tune SFX during gameplay. A nice introductory tune though is included and written by the all known Chris Hülsbeck, the great composer of the Turrican series (and lot more).
