Classic Game Room reviews YASI for the Vectrex released in 2003, a homebrew game that plays a lot like the classic Space Invaders (in fact, pretty much identical). The package seen here has custom art by the way. Blast those invaders from space on this sweet Vecrex homebrew game that comes with Protector, a clone of another game where you defend things. CGR Yasi review was recorded from Vectrex at the Intergalactic 70s Space Bar!.
