Play Insector X (Japan) Online

Insector X came out on the NES in 1989, developed by Hot-B. It was part of that wave of side-scrolling shooters that filled the library, offering another take on the familiar run-and-gun formula without trying to reinvent the wheel.

You pilot a small, agile ship through six levels of insect-themed chaos, shooting everything that moves. Your main goal is to survive the onslaught and defeat each stage's boss. A key mechanic is the power-up system: collect colored orbs to change your weapon type, like spreading shots or lasers, and these can be stacked for increased firepower. The game is fast and often overwhelming, with enemies swarming from all directions and screen-filling bosses that demand quick reflexes. Despite the constant pressure, weaving through bullet patterns and unleashing upgraded weapons gives a satisfying sense of control amid the frenzy.
