Invasion (S02E12)

The sliders land in the thick of an invasion. A desolate world greets them, graffiti litters the ravaged walls announcing the coming of the "Kromaggs". An electrical field is being projected from an alien ship on the same wavelength as the timer. Quinn (Jerry O'Connell) is able to use it to jam the ship's controls causing the vessel to crash. Arturo and Quinn enter the damaged vessel only to find things are not as they appear. (iTunes)
