Play BS Ikari no Yousai (Japan) Online

BS Ikari no Yousai is a 1993 Super Nintendo Entertainment System game, released only in Japan as part of the Broadcast Satellaview service. Developed by Nintendo R&D1 and published by Nintendo, it fits into the SNES library as an experimental, defense focused title that used real time data broadcasts to deliver episodic content.

You control a cursor to place and upgrade defensive units, like cannons and walls, along a fortress perimeter. The main objective is to survive waves of enemy soldiers and vehicles that advance from both sides of the screen. Signature mechanics include managing limited resources between rounds, strategically reinforcing vulnerable sections, and reacting to enemy types that require specific counters. The pacing is methodical under pressure, and the difficulty can feel punishing if your placements are inefficient. It feels like a tense puzzle where every decision matters right up to the last second.
