The game requires the player to maneuver the excavation probe, through a first-person view, through eighteen regions (in the shape of a rhombicuboctahedron) of the moon Mitral, and place a drilling rig in each of them to allow a minimum of 50% of the gas to escape. The position is established by a mixture of clues from the landscape (including an "X marks the spot" in the first zone) and trial and error. The security systems will attack Lesleigh upon sight, and he must disable or avoid them by any means possible. Only a few can be destroyed by shooting, the rest must be dispatched by mechanical means through switches or similar.
The eighteen regions are actually platforms above the true surface of Mitral; the excavation probe cannot fly or hover (although it can rise and lower itself slightly on hydraulics), and moving off a platform causes the player to fall onto the surface, where he is marooned. However, in one area the player can find a garage containing a hovering vehicle that can be used to explore and attack security systems, though not to place drilling rigs.
The driller is a team leader in charge during the process of well drilling. The term is commonly used in the context of an oil well drilling rig.
The driller is in charge of the crew, and running the rig itself. Most of the time, his or her job is simply to monitor the rig's activity, while the automatic driller runs the breaks and drills the hole. The driller is responsible for interpreting the signals the well gives regarding gas and fluids with high pressure. In an emergency he is also responsible for taking the correct counter measures to stop an uncontrolled well control situation from emerging. The driller will watch for gas levels coming out of the hole, how much drilling mud is going in, and other information. While tripping, the driller will run the floor and work the rig.
In the context of an offshore oil platform, the driller will be the one in charge of real time decisions. According to and, the hierarchy on an oil platform correspond to the timescale of which the sections operate. The automatic drilling equipment work on the timescale of seconds and both reports to and gets its orders from the driller, who operates on a timescale of several seconds to hours. The person will report and gets his or her orders from those planning the current drilling operation, on a timescale of days and weeks. The chain extends to those who are in charge of managing the whole oil field, on a timescale of decades.
At the start of the series, Tyrol is romantically involved with LieutenantSharon "Boomer" Valerii aboard Galactica, who is, unbeknownst to either Tyrol or herself, a Cylon. Once Sharon's true nature is revealed when she attempts to assassinate then-Commander Adama, Tyrol is accused of being a Cylon and is thrown into the brig with Sharon. He claims he hates her and orders her to keep her distance, but when Sharon is shot and killed by Cally, he mourns her and reveals his true affection for her. Tyrol is "proven" not to be a Cylon - for the time being - and resumes his job. Discovering the existence of Caprica-Valerii (who is pregnant and in love with Helo) confuses him, especially with Galactica-Valerii's death still haunting him.
In heraldicblazon, a chief is a charge on a coat of arms that takes the form of a band running horizontally across the top edge of the shield. Writers disagree in how much of the shield's surface is to be covered by the chief, ranging from one-fourth to one-third. The former is more likely if the chief is uncharged, that is, if it does not have other objects placed on it. If charged, the chief is typically wider to allow room for the objects drawn there.
The chief is one of the ordinaries in heraldry, along with the bend, chevron, fess, and pale. There are several other ordinaries and sub-ordinaries.
Variations of chief
The chief may bear charges and may also be subject to variations of the partition lines. The chief may be combined with another ordinary, such as a pale or a saltire, but is almost never surmounted by another ordinary. The chief will normally be superimposed over a bordure, orle and tressure, if they share the same shield.
