NOVA STRIKER vs OUTBREAK SURVIVOR

A retro '90s-style vertical bullet-hell shooter you can play with one finger — free, and fully playable offline. Weave through walls of bullets across 3 stages and massive boss battles. Skim past enemy fire to "graze" for score and bomb gauge, and turn the tables with screen-clearing bombs. Clear everything, and a hidden true battle awaits. ◆ Features - Intuitive controls: drag to move, auto-fire, double-tap to bomb — one-handed play - Graze system: near-misses are the path to high scores - 3 stages + more: unique midbosses, bosses, and a hidden final boss - Achievements & rankings: 14 achievements and global rankings (with per-language boards) - Difficulty options: EASY / NORMAL / HARD - 17 languages supported, works offline ◆ How to Play 1. Drag to move (your ship fires automatically) 2. Double-tap to trigger a bomb (clears enemy bullets) 3. Graze enemy bullets for bonus score 4. Watch a short video to revive after game over and push on for the clear Note: This game contains flashing lights. Player discretion is advised for those with photosensitivity. ◆ Made for players who enjoy - A retro arcade shooter, pixel art, neon lights, and a tense trip through space - A quick game during a break, or a longer high-score and score-attack session at home - Learning to dodge patterns with one hand in portrait mode instead of aiming every shot - Starting on EASY, settling into NORMAL, then taking on the hardcore density of HARD ◆ A score run with choices NOVA STRIKER is a danmaku-style shmup where reading a pattern matters as much as reflexes. Your ship fires on its own, leaving you free to steer through the gaps. A close dodge earns graze and fills the bomb gauge, so a daring line can be worth more than a safe one. Spend a bomb to clear a crowded screen, or save it for a boss phase: each run is a chance to refine that decision. ◆ Reasons to return The three stages are built around distinct enemy waves, midbosses, and boss battles, culminating in the hidden final boss. Choose the pace that suits you: EASY introduces the flow, NORMAL rewards consistency, and HARD asks for careful routing through thicker bullet patterns. Chase all 14 achievements, improve your high-score, and compare results on global leaderboards with separate boards by language. ◆ Play on your terms This is a free single-player action game for portrait smartphones, designed for a few spare minutes or repeated practice. It works offline, so a connection is not required to fly and dodge. A rewarded video is offered only when you choose to revive after game over; there are no forced ads interrupting play. With drag movement, auto-fire, and a double-tap bomb, it stays focused on the arcade rhythm. Price: Free to play, with one optional one-time purchase (rewarded ads only — no forced ads) Supports: Smartphones (portrait)
