Minus Zero | Mythic Sword

Summary pulled directly from Steam - Some text may only be applicable to Steam platform

Triangle Service’s MINUS ZERO is an abstract, minimalist shooter that focuses on a tried-and-true shoot-’em-up weapon: the lock-on laser. It’s shoot-’em-up purity: just you, your lock-on laser, and a whole bunch of enemies. As long as you continue to blast away at the waves of enemies, you’ll maintain invincibility, but if you lose track of your position among the explosions and neon glow, you’ll soon find that invincibility can be fleeting!

Features:

Lock onto invincibility in this abstract, minimalist shoot-’em-up
Glowing neon aesthetic that actually adds to the challenge
Replay support
Electronica soundtrack that builds upon itself as you progress
Includes Achievements, Leaderboards, and Cloud saves
