Liero is a video game for MS-DOS, first released by Finnish programmer Joosa Riekkinen in 1998. The game has been described as a real-time version of Worms (a turn-based Artillery game). It has many weapons and sounds from its precursor, MoleZ. 'Liero' is Finnish for earthworm and is pronounced [liero]. Later on, this game provided inspiration for the game Soldat.
In Liero, two worms fight each other to death for score (or frags) using a choice of five weapons from a total of 40 in a two-dimensional map. Most of the terrain, except for indestructible rocks, may be dug or destroyed by explosions. In addition to the weaponry, each player has a ninja rope which can be used to move faster through the map. This grappling hook-like device substitutes for jetpacks and can even latch onto the enemy worm to drag him closer to his foe.
While playing, there are health power-ups to heal your worm. It is also possible to replace one of your five weapons by picking up bonuses. Before playing, you can select certain weapons to be available only in bonuses, in the entire game, or completely disabled.
The horizon or skyline is the apparent line that separates earth from sky, the line that divides all visible directions into two categories: those that intersect the Earth's surface, and those that do not. At many locations, the true horizon is obscured by trees, buildings, mountains, etc., and the resulting intersection of earth and sky is called the visible horizon. When looking at a sea from a shore, the part of the sea closest to the horizon is called the offing. The word horizon derives from the Greek "ὁρίζων κύκλος" horizōn kyklos, "separating circle", from the verb ὁρίζω horizō, "to divide", "to separate", and that from "ὅρος" (oros), "boundary, landmark".
Historically, the distance to the visible horizon at sea has been extremely important as it represented the maximum range of communication and vision before the development of the radio and the telegraph. Even today, when flying an aircraft under Visual Flight Rules, a technique called attitude flying is used to control the aircraft, where the pilot uses the visual relationship between the aircraft's nose and the horizon to control the aircraft. A pilot can also retain his or her spatial orientation by referring to the horizon.
In the Stargate fictional universe, the humans of Earth have developed many advanced technologies based on what SG teams have brought back from trips to other planets through the Stargate. Earth has also benefitted from technical knowledge provided by friendly alien races, such as the Asgard and the Tok'ra.
The producers of Stargate SG-1 and Stargate Atlantis collaborated closely with the United States Air Force. The USAF is portrayed in a positive light in the series; as a result the franchise received access to USAF weaponry and fighter jets. The Oregon Air National Guard 173rd FW from Kingsley Field in Klamath Falls, OR provided F-15 fighter jets for the movie Stargate: Continuum. The FN P90 was the favoured weapon of SG-1, and replaced the Heckler & Koch MP5 that was used until season 4 of Stargate SG-1. The P90 is also used by teams on Stargate Atlantis. In seasons 9 and 10 of SG1, the teams can be seen using other firearms, including the G36 and MP7. All personnel appear to be issued the Beretta 92, which they used throughout the series.
