Play Viper Phase 1 Online
Dodging neon bullets in a 90s arcade spaceship feels like threading a needle while fireworks go off—then the boss laughs and wipes you out. Those chunky pixels still make chaos beautiful.

Viper Phase 1, released by Seibu Kaihatsu in 1995 and playable via MAME 0.243, is a vertical-scrolling shooter from the arcade era. It fits right in with the mid-90s trend of intense, screen-filling action, where developers pushed hardware to its limits with detailed sprites and relentless enemy waves.
You pilot a fighter ship through waves of enemies, clearing each screen before advancing. The main goal is survival, navigating intricate bullet patterns while collecting power-ups to enhance your weapons. Signature mechanics include a chargeable shot that builds in strength the longer you hold fire, and a proximity-based bomb that clears nearby bullets when triggered. The pacing is fast, and the difficulty quickly escalates, demanding sharp reflexes and memorization. It feels like a tense, high-stakes dance through fields of glowing projectiles.
