Hydorah creator Locomalito has released Verminest, a free, retro-styled homage to Namco's classic arcade shoot-'em-up Galaga.

Along with wave-based Galaga gameplay, Verminest also features vertically scrolling sequences straight out of Galaga '88, along with boss fights that pay tribute to fellow classics like Centipede. The greyscale sci-fi motif cites inspiration from a number of films, including Them!, The Deadly Mantis, and Godzilla.

There's also a 3D mode, if you want to complete the '50s drive-in experience. Red-and-blue glasses are not included.

A bunch of fun supplemental material is also available alongside the free game download at Locomalito's site, including promotional posters, trading cards, and a making-of featurette.
