Juno First (ジュノファースト) is a shoot 'em up arcade game developed by Konami and released in 1983. It was licensed to Gottlieb in the United States. The game is a vertical scrolling shooter, with a third-person perspective like Radar Scope. It follows in the tradition of space-themed shooting-galleries such as Space Invaders and Galaga. Juno First, however, is notable for its frenetic gameplay (like Defender and Xevious).
Juno First presents a set number of enemies per level, but they do not make a gallery formation. This is not a typical gallery shooter. Instead, the player's ship can move forward and backward (in addition to left and right) to hunt enemies in an orientation that is vertical, but has some horizon-oriented tilt. This style of gameplay would be re-used in a later Konami shooter, Axelay.
The player destroys waves of enemies to finish levels. Starting formations vary from stage to stage. In addition, the player can pick up a humanoid, upon which the screen will have a red tint. While this happens, every enemy the player shoots will earn the player 200 more points than the previous enemy destroyed. The original score for shooting an enemy while in humanoid mode depends on the stage.
