Built off of a heavily modified version of the Quake engine, Half-Life boasts much-improved graphics, artful ingame scripted sequences and one of the most immersive storylines of any game to date! Gameplay includes a mix of intense action-oriented combat and various puzzles, all combined in a continuous and immense world.

Players find themselves in the shoes of Dr. Gordon Freeman, a theoretical physicist who inadvertently triggers the horrific incident known as the 'resonance cascade' while performing an experiment, causing massive destruction, death and an alien infestation of the entire Black Mesa Research Facility. With a trusty crowbar (and a slew of other weaponry he finds on the way) and all the help he can get, Gordon finds himself pitted against both the aliens from the planet Xen and a dangerous military force known as the Hazardous Environment Combat Unit—who were dispatched to clean up the situation&mdashscientists included! Can he get out alive?

half-life

(hăf′līf′, häf′-)n.
1. Physics The time required for half the nuclei in a sample of a specific isotopic species to undergo radioactive decay.
2. Biology
a. The time required for half the quantity of a drug or other substance deposited in a living organism to be metabolized or eliminated by normal biological processes. Also called biological half-life.
b. The time required for the radioactivity of material taken in by a living organism to be reduced to half its initial value by a combination of biological elimination processes and radioactive decay.

half-life

n
1. (General Physics) the time taken for half of the atoms in a radioactive material to undergo decay. Symbol: τ
2. (Biology) the time required for half of a quantity of radioactive material absorbed by a living tissue or organism to be naturally eliminated (biological half-life) or removed by both elimination and decay (effective half-life)

half-life

(hăf′līf′)
The average time needed for half the nuclei in a sample of a radioactive substance to undergo radioactive decay. The half-life of a substance does not equal half of its full duration of radioactivity. For example, if one starts with 100 grams of radium 229, whose half-life is 4 minutes, then after 4 minutes only 50 grams of radium will be left in the sample, after 8 minutes 25 grams will be left, after 12 minutes 12.5 grams will be left, and so on.

half-life

The time required for the activity of a given radioactive species to decrease to half of its initial value due to radioactive decay. The half-life is a characteristic property of each radioactive species and is independent of its amount or condition. The effective half-life of a given isotope is the time in which the quantity in the body will decrease to half as a result of both radioactive decay and biological elimination.
Dictionary of Military and Associated Terms. US Department of Defense 2005.

half-life

1. A substance which undergoes exponential decay decays by the same ratio in equal intervals of time. The constant ratio is the half-life. The rate of radioactive decay of a substance is defined by its half-life.
2. The time in which half the atoms in a radioactive isotope decay.
Dictionary of Unfamiliar Words by Diagram Group Copyright © 2008 by Diagram Visual Information Limited
Noun1.half-life - the time required for something to fall to half its initial value (in particular, the time for half the atoms in a radioactive substance to disintegrate)
period, period of time, time period - an amount of time; 'a time period of 30 years'; 'hastened the period of time of his recovery'; 'Picasso's blue period'
