Team Fortress 2 is a team-based first-person shooter multiplayer video game developed and published by Valve Corporation. It is the sequel to the 1996 mod Team Fortress for Quake and its 1999 remake. It was released as part of the video game compilation The Orange Box on October 10, 2007 for Windows and the Xbox 360. A PlayStation 3 version followed on December 11, 2007. On April 8, 2008, it was released as a standalone title for Windows. The game was updated to support OS X on June 10, 2010, and Linux on February 14, 2013. It is distributed online through Valve's download retailer Steam; retail distribution was handled by Electronic Arts.
In Team Fortress 2, players join one of two teams comprising nine character classes, battling in a variety of game modes including capture the flag and king of the hill. The development is led by John Cook and Robin Walker, creators of the original Team Fortress. Announced in 1998, the game once had more realistic, militaristic visuals and gameplay, but this changed over the protracted nine-year development. After Valve released no information for six years, Team Fortress 2 regularly featured in Wired News' annual vaporware list among other ignominies. The finished Team Fortress 2 has cartoon-like visuals influenced by the art of J. C. Leyendecker, Dean Cornwell and Norman Rockwell and is powered by Valve's Source engine.
Pyro (St. John Allerdyce) is a fictional supervillain appearing in American comic books published by Marvel Comics. He is a recurring enemy of the X-Men and later becomes an agent of the U.S. government. He was created by Chris Claremont and John Byrne and introduced in Uncanny X-Men #141 (January 1981) as part of the Brotherhood of Evil Mutants. Pyro had the mutant ability to control fire.
Pyro and the Brotherhood of Evil Mutants are the main antagonists in the Days of Future Past in the X-Men comics as they attempt to assassinate Senator Robert Kelly, which in an alternate timeline leads to a dystopic future where Mutants are hunted, killed or captured by the Sentinels robots. Through time travel the assassination was thwarted.
At a later date the Brotherhood becomes agents of the US government in exchange for a full pardon and the team becomes known as the Freedom Force. While working for the government the team confronts both the X-Men and the Avengers. During a mission to Kuwait Pyro is captured by the enemy. Pyro contracted the Legacy Virus, fatal to all mutants, moments before his death Pyro saved Senator Kelly from another assassination attempt, changing Kelly's anti-mutant stance. Pyro was later resurrected by the Transmode Virus, existing as a techo-organic being under Selene's control.
In particle physics, antimatter is material composed of antiparticles, which have the same mass as particles of ordinary matter but opposite charges, as well as other particle properties such as lepton and baryon numbers and quantum spin. Collisions between particles and antiparticles lead to the annihilation of both, giving rise to variable proportions of intense photons (gamma rays), neutrinos, and less massive particle–antiparticle pairs. The total consequence of annihilation is a release of energy available for work, proportional to the total matter and antimatter mass, in accord with the mass–energy equivalence equation, E = mc2.
Antiparticles bind with each other to form antimatter, just as ordinary particles bind to form normal matter. For example, a positron (the antiparticle of the electron) and an antiproton (the antiparticle of the proton) can form an antihydrogen atom. Physical principles indicate that complex antimatter atomic nuclei are possible, as well as anti-atoms corresponding to the known chemical elements. Studies of cosmic rays have identified both positrons and antiprotons, presumably produced by collisions between particles of ordinary matter. Satellite-based searches of cosmic rays for antideuteron and antihelium particles have yielded nothing.
Antimatter is material composed of antiparticles in the same way normal matter is composed of particles.

Antimatter, a UK melancholic rock band, is the project of longtime member Mick Moss. The project was formed in 1997 by Duncan Patterson (former bassist/songwriter of Anathema) and Moss. The pair released three albums together - Saviour, Lights Out and Planetary Confinement. Shortly after the completion of Planetary Confinement, Patterson left to start another band called Íon. Moss continued and released the project’s fourth album, Leaving Eden, following with 2009’s Live@An Club, released on his own label Music In Stone. Most recently Moss has overseen a 10 year retrospective multi-disc release entitled ‘Alternative Matter’, and released the 5th Antimatter album, 'Fear Of A Unique Identity', in 2012.
The earlier Antimatter albums, Saviour and Lights Out, focused on melodic vocal lines (often by guest female vocalists), dark electronica and balanced on the borderline between gothic and trip hop. Planetary Confinement marked the start of a shift towards more of an acoustic based melancholic rock sound. Leaving Eden, with Mick Moss as the only songwriter and singer, continues in this direction and also gives electric guitars a more prominent role. The result is a heavier sounding album, with little trace of the ambient sound of early Antimatter. Recent album Fear Of A Unique Identity presents a more layered, energetic picture, mixing all of Antimatter's past textures with a New Wave feel.
