Xevious is a landmark arcade game from Namco in 1982, and one of the first vertical scrollers to distinguish between air and ground targets: your gun handles what's flying, and a separate bomb with its own targeting reticle handles what's on the ground.
That two-weapon system was genuinely novel, and it's what makes the game more than a reflex test — you're tracking two threat layers at once and choosing which to answer.
It was one of the first vertical shooters to separate air and ground targets, giving you two weapons with different targeting — a design that shaped the genre after 1982.
A targeting reticle sits ahead of your ship. Because the terrain scrolls toward you, you drop bombs before the target is under you.
Yes — a light arcade game with nothing to install.
