Mass Effect 2

Mass Effect 2 is an action role-playing video game developed by BioWare and published by Electronic Arts. It was released for Microsoft Windows and Xbox 360 on January 26, 2010, and for PlayStation 3 on January 18, 2011. Mass Effect 2 is the second installment of the Mass Effect series and a sequel to the original Mass Effect. The game takes place within the Milky Way galaxy during the 22nd century, where humanity is threatened by an insectoid species known as the Collectors. The player assumes the role of Commander Shepard, an elite human soldier who must construct and gain the loyalty of a diverse team in order to defeat the enemy in a suicide mission. With the use of a completed saved game of its predecessor, the player can impact the story of the game in numerous ways.

For the game, BioWare changed several gameplay elements and put further emphasis on third-person shooter aspects, including limited ammunition and regenerable health. In contrast to the exclusive focus on the main story of the original Mass Effect, the developers opted to create a plot where optional missions had as much intensity as the main mission. Mass Effect composer Jack Wall returned to compose Mass Effect 2's music, aiming for a darker and more mature sound to match the mood of the game. Mass Effect 2 also supports a variety of downloadable content packs that were released from January 2010 to May 2011. The downloadable content ranges from single in-game character outfits to entirely new plot-related missions. Notable packs include Overlord, Lair of the Shadow Broker, and Arrival.

Mass Effect

Mass Effect is a science fiction action role-playing third person shooter video game series developed by the Canadian company BioWare and released for the Xbox 360, PlayStation 3, and Microsoft Windows, with the third installment also released on the Wii U. The fourth game will release on Microsoft Windows, PlayStation 4 and Xbox One.

The original trilogy largely revolves around a soldier named Commander Shepard, whose mission is to save the galaxy from a race of powerful mechanical beings known as the Reapers and their agents, including the first game's antagonist Saren Arterius. The first game sees Shepard investigating Saren, whom Shepard slowly comes to understand is operating under the guidance of Sovereign, a Reaper left behind in the Milky Way tens of thousands of years before, when the Reapers exterminated virtually all sentient organic life in the galaxy as part of a recurrent cycle of genocide for an unknown purpose. Sovereign's purpose is to trigger the imminent return of the Reaper fleet hibernating in extra-galactic dark space, restarting the process of extermination. The second game takes place two years later, and sees Shepard battling the Collectors, an alien race abducting entire human colonies in a plan to help the Reapers return to the Milky Way. The final game of Shepard's trilogy centers on the war waging against the Reapers.

Mass

In physics, mass is a property of a physical body. It is generally a measure of an object's resistance to changing its state of motion when a force is applied. It is determined by the strength of its mutual gravitational attraction to other bodies, its resistance to being accelerated by a force, and in the theory of relativity gives the mass–energy content of a system. The SI unit of mass is the kilogram (kg).

Mass is not the same as weight, even though we often calculate an object's mass by measuring its weight with a spring scale instead of comparing it to known masses. An object on the Moon would weigh less than it would on Earth because of the lower gravity, but it would still have the same mass.

For everyday objects and energies well-described by Newtonian physics, mass describes the amount of matter in an object. However, at very high speeds or for subatomic particles, special relativity shows that energy is an additional source of mass. Thus, any stationary body having mass has an equivalent amount of energy, and all forms of energy resist acceleration by a force and have gravitational attraction.
