The year is 1979. A secret, final lunar mission has retrieved hundreds of moon rocks, carried out by order of high-level overseers at the Aether Research Facility. The more we begin to understand about our universe, the more deadly it becomes. Overtaken by curiosity, researchers delve deeper and deeper into the unknown, only to find what we think we understand about the cosmos, is terribly incorrect. The research and experiments reach a tipping point, specimens begin to escape, and researchers scramble to leave the secret base. Most leave unscathed, while others lose their lives in an attempt to flee from the deadly forces that lie within. In the panic, fear, and confusion of countless emergency distress signal codes, help is requested. The distress signal is unintentionally received by the government's haz-mat cleanup division. A small team of three is sent to carry out what they believe to be a simple routine clean-up. They are sorely mistaken. What lies within the facility becomes increasingly darker the deeper one pursues the truth.

The Milky Way has fallen under the iron fist of galactic empires. In Quadrant M4, the final bastion of humanity, you are the last hope. Implanted cybernetics control the masses, but you have resisted assimilation. Now, you have infiltrated the enemy's exposed forward research facility. Your mission: commandeer the Sar-On BattleStar prototype and sever their supply lines. Engage in intense space combat across two dozen star systems. Disable the crucial warp gates to trap the Sarkad and Onton fleets in Andromeda, turning the tide of their expansionist war. But time is running out!

The pillars of light and color have sunk beneath the ocean, and an ashen gray has overcome the world - raise them back up by putting your logical thinking and deductive reasoning to the test.

Quake II is a year old, but the new weapons and power-ups make the game interesting again.

TeamFortress is a new QuakeC mod which radically changes team games. It provides far more incentive for teams to actually work as a team. Each member of the team has unique weapons, items, and abilities, and style of play. Class Descriptions SCOUT The Scout is the fastest moving class of all, and the lightest armored. He can wear a maximum of 50 green armor. He only carries the axe, single-barrel shotgun, and the nailgun, and has a low ammo-carrying capability. His grenade types are Flash and Concussion, both not very useful for damaging enemies, but useful for escaping from enemies. He is the ideal class for swift recon and flag capturing, and his grenades are a good way to sow confusion among enemy ranks, allowing for easy kills from supporting teammates. A scout can disarm detpacks by simply running over them, although it does take a couple of seconds. A scout can also detect undercover enemy spies when he comes into contact with them. SNIPER The Sniper class moves at a medium speed, and wears as little armor as the Scout: a maximum of 50 green armor. He carries the axe, nailgun, and Sniper Rifle. His grenade types are Hand and Flares. His sniper rifle makes him the ideal class for long-distance defense, but his lack of close-range weaponry means he's got trouble if the opponent should get within range. SOLDIER The Soldier class is the basis of a TF team. He moves slower than most classes, but makes up for it with the weaponry and armor he carries. He can wear a maximum of 200 red armor. He uses the axe, the shotgun, the super shotgun, and the rocket launcher. His grenade types are Hand and Nail. A versatile class, the soldier has no real specialisation... but he's the core of any offensive or defensive squad. DEMOMAN The Demolitions Man moves at medium speed, and wears an average amount of armor. He can wear a maximum of 100 yellow armor. He uses the axe, the shotgun, and the grenade/pipebomb launcher. His grenades types are Hand and Mirv. At close range, the demoman is particularly dangerous... his main weapons are his launcher and hand/mirv grenades, and with them he can clear rooms in seconds. But at long range, he's in trouble. Due to his speed and weaponry, he's a good offensive class... but with his pipebombs and mirvs, he's often used as the last line of defense. COMBAT MEDIC The Combat Medic is a medium speed class with average armor. He can wear a limit of 100 yellow armor. He uses the medikit/bioweapon, the shotgun, the super shotgun, and the super nailgun. His grenade types are Hand and Concussion. A good class in most situations, the medic is good at close or medium range, and packs enough punch to kill any of the lesser-armored classes. A good addition to offensive teams, and an even better addition to defensive groups through his use of the medikit. A great class for clearing out snipers that are pinning a team down. HEAVY WEAPONS GUY The Heavy Weapons Guy is the slowest moving and most heavily armored class. He can wear a limit of 250 red armor. He uses the axe, the shotgun, the super shotgun, and the assault cannon. His grenade types are Hand and Mirv. An almost purely defensive class, the heavy weapons guy can kill any fully armored enemy with a few seconds of concentrated fire from the assault cannon. Mainly effective in open areas, he can be killed by weaker classes if they've got plenty of cover, due to the time taken for the assault cannon to spin up and down. PYROMANIAC The Pyro is a medium speed, well armored class. He can wear a maximum of 150 yellow armor. He uses the axe, the shotgun, the flamethrower, and the incendiary cannon. His grenade types are Hand and Napalm. A good support class, the Pyro often finds it hard to kill enemies on his own. Given time, most enemies burn to death, but in that time the Pyro's probably been killed. Due to his ability to knock chunks off the enemy, the Pyro is a great first line of defense. Any enemy getting past him will almost certainly be half dead. SPY The Spy is a medium speed, fairly lightly armored class. He can wear a maximum of 100 green armor. He uses a knife, a tranquiliser gun, the super shotgun, and the nailgun. His grenade types are Hand and Hallucogenic. A fantastic infiltration class, the Spy can often get inside incredibly well defended bases. His limited weaponry make him a weak fighter if the enemy is aware of his presence... but if they're unaware, he can kill them before they can blink. ENGINEER The Engineer is a medium speed, fairly lightly armored class. He can wear a maximum of 50 yellow armor. He uses a spanner, a railgun, and the super shotgun. His grenade types are Hand and EMP. A good defensive class, the engineer works primarily as a support class. With his ability to repair armor, create ammo, and build structures, the engineer increases the strength of a group of defenders tenfold.

You get the phone call at 4 a.m. By 5:30 you're in the secret installation. The commander explains tersely, "It's about the Slipgate device. Once we perfect these, we'll be able to use them to transport people and cargo from one place to another instantly. An enemy codenamed Quake, is using his own slipgates to insert death squads inside our bases to kill, steal, and kidnap. The hell of it is we have no idea where he's from. Our top scientists think Quake's not from Earth, but another dimension. They say Quake's preparing to unleash his real army, whatever that is. "You're our best man. This is Operation Counterstrike and you're in charge. Find Quake, and stop him...or it... You have full authority to requisition anything you need. If the eggheads are right, all our lives are expendable." While scouting the neighborhood, you hear shots back at the base. Damn, that Quake bastard works fast! He heard about Operation Counterstrike, and hit first. Racing back, you see the place is overrun. You are almost certainly the only survivor. Operation Counterstrike is over. Except for you. You know that the heart of the installation holds a slipgate. Since Quake's killers came through, it is still set to his dimension. You can use it to get loose in his hometown. Maybe you can get to the asshole personally. You pump a round into your shotgun, and get moving." From the masterminds behind DOOM and Wolfenstein comes an FPS classic that will warp your world. Building on the successful elements that drew players to DOOM, Quake brings a more Gothic flavour to the FPS genre and, like its predecessor, has spawned copycats and sequels over the years. The game is also renowned for creating and popularising Machinima, as the game engine was used to create Machinima classic's such as "The Diary of a Camper" and "The Seal of Nehahra". This GOG release also contains the two expansions for this first installment, "Quake Mission Pack No. 1: Scourge of Armagon" and "Quake Mission Pack No. 2: Dissolution of Eternity", bringing even more interdimensional horrors and weapons to your PC. With the main game soundtrack composed by Trent Reznor, you're in for one heart-stopping hell of a ride. * 4 difficulties to choose from * Battle and explore your way through over 60 levels * Ghoulish Gothic atmosphere enhanced by a captivating soundtrack
