Play Viper Phase 1 Online
Pilot your fighter ship, dodge enemy waves, collect power-ups, and unleash charged shots in this vertical-scrolling shooter from 1995.
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.
