Zanac has some things that are subjective:
- Demonic Spiders
- Round Cores in the original, when they're fully open. They release projectiles which spin around, soak up quite a few damage and can overwhelm the player.
- Also, for normal aerial enemies, purple Lusters which fly around with a wise arc and that means usually firing its projectiles behind the player.
- Jack the Dynamic Difficulty high enough and you get these annoying blue enemies that line up with you and shoot out a constant stream of missiles. Flying above them will NOT help because they can fire upwards too.
- Game Breaker: Weapon 7. Fires fast, can move left and right at a limited angle, and can go through enemies. Very powerful, but is also a bit of a rarity.
- The FC-Custom in Neo. It's basically an Homage to the original Zanac fighter that is unlocked through either a code or having a save file of the original Zanac game, and it plays exactly like the original down to the weapons degradation system, so no blast mode or charge shots. However, all of its subweapons can destroy enemy shots, and this is a ship that, with weapon 7, can rip the crap out of anything. For reference, the regular Neo ships can only destroy enemy shots through sacrificing offense for defense, something that ramps up the Dynamic Difficulty. Oh, and it benefits from the Landers, having an insane rate of fire if exploited right.
- Weapon 6 in Neo is an explosive that shreds most enemies and lingers long enough to take out multiple targets, but is extremely slow and the firing rate is abysmal. Power it up to max, though, and you get a massive Sphere of Destruction that wrecks everything it touches (including bosses,) and the firing rate problem can be solved by just getting up in your target's face and unleashing it point blank.
- Goddamned Bats - Although many of the enemies qualify, T-Cells, which appear in Areas 8 and 11 in the original game, are perhaps the best examples. They cannot be killed with anything that doesn't clear the screen, they block shots completely and have to be destroyed by bumping into them.
- Goddamned Boss - Capital ships in the original game since almost all projectiles bounce off of it (although still damaging it), lowering your fire rate considerably. In addition, all but one of those will actually home on ship.
- Most Wonderful Sound - The extra life sound. The Neo variant even has a ringtone for it in Japan.
- Scrappy Weapon: Weapon 2 in Zanac, a shield that lasts for 50 uses, can be recharged by collecting more '2' items, but also triggers the Dynamic Difficulty's Berserk Button.
- Sequel Displacement - In fact the the first port was the MSX one.
- Stop Helping Me!: During later boss fights, both games can get a little overzealous with hurling power-up blocks at you, to the point that you can't even hit the boss.
