Formido is one of those games, where you are loaded with some guns and you go shooting different things. "Things" in this case are big, ugly, – not green though – alien insects. The idea is to kill as many of those bastards as possible. Eventually they will overcome you, but struggle as long as you can. There are some power-ups to aid you in your honorable quest. Keep in mind, that those critters are rather tough and generally do nasty things when in close range of any player-characters.
