Based on a mythical vector arcade machine of the late 1980s that was never released, Vector-Z is a space shooter with advanced vector graphics and particle systems designed to dazzle your senses… it's as if the 1980's arcades never went away and the games kept getting better. Vector-Z is a unique, retro-style arcade game with glowing multicolor vector-graphics, analog synthesized sounds, and a retro soundtrack with amazing spaced out tunes to zap extraterrestrial invaders to. Some of Vector-Z's aliens have shields you have to time your shots to break through. There’s also an asteroid bonus level where you can break up asteroids for points, and break up bigger asteroids for power-ups, including bonus shields, extra lives, score multiplier, and a faster fire rate. HINTS: • Vector-Z’s ship holds 2 missiles. One fires from each wing, so there’s a slight offset. There is also a brief reload time. • Aliens are worth more points when they are attacking you. Even more points when they are really close! • Go for the bonus points from accuracy: at 50% you get 100 pts per hit, 200 pts at 75%, 400 pts at 90%, and 800 bonus pts per hit with 100% accuracy! • Aim for the bigger asteroids to collect hexagonal power-ups Vector-Z is compatible with iCade, and requires iOS 7.1 or later.

Verdict

The call

The clearest difference is review sentiment: Only One at 100% against Vector's 40%. Only One also leads on rating (5.0 vs 4.2). Vector's advantage is update cadence (every 6 weeks vs every 39 months) and ratings volume (10 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
