About this game
Invaders 1978 recreates the movement-and-shooting rhythm of the early arcade game. Move beneath the alien formation, avoid falling shots and fire upward before the invaders reach the ground. As the formation thins out, the remaining targets become faster, making the final few enemies more demanding than the opening row.
The DOS game first appeared in June 1996. This page uses its v02 update from December 2000, identified by the bundled executable and release history. The title refers to the arcade inspiration, not the release year of this PC program.
Use Left Ctrl to move left, Left Alt to move right and Right Shift to fire. These are the bindings documented for this v02 release. This release does not offer key reassignment. Escape stops the program. Get comfortable with the three-key layout before the wave speeds up, rather than assuming the arrows and Space are used.
