1.
The main protagonist of the video game series Half-Life. He has starred in both games in the series. He's acquierd a PHD in Theoretical Physics from MIT. He had always been a genius. He was asked to join a team of scientists working on new weapons and tools in the subterranean complex called Black Mesa, located in New Mexico. When he joined up, all hell broke loose. On one of his routine scavanging hunts in another dimension, the calibrations for the teleportation were miscalculated. Upon the atempted entering of the portal, Gordon caused a rift, a "rip" in the dimension, sending many of its creatures to our world. These creatures infested the Black Mesa facility. Soon Gordon had to escape to the surface if he hoped to survive. He fought against various alien adversaries until he finally met the military. All of the scientists thought they were there to help; no, they were there to contain it, by killing every man and woman involved in Black Mesa. So, now Gordon had to fight against the military, on top of the invaders. He made it to the surface and had to eventually go back into the facility to meet up with the team at the Lambda complex. His fellow scientists teleported him to the rift world "Xen," where these creatures were coming from. He fought through world after world and made it to the great superpower that was behind the Resonance Cascade (the rip in the dimension). It was called Nihilanth. He battled the creature until he finally destroyed it. He then was once more teleported, this time to the same train that he rode into work on. Before him stood a strange government figure dressed in a blue suite carrying a brief case. This Gman offered Gordon a job to work for him. He could either accept it, or die. Gordon accepted this mission and blacked out.

Some time later he woke up on a train. He was in a place called City 17. Gordon didn't know how long it had been since the Black Mesa incident. He had seen the Gman in a dream. Gordon went through the city. It was ruled by strange men in gas-masks. These were called the Combine. He made it to an old friend's lab and he was told about the resistance, and how some of his colleagues escaped from Black Mesa. He rode upon an airboat accross a great river. He was then brought to the lab of Eli Vance, one of the leaders of the resistacne. He then went to Ravenholm, a ghost town overrun by headcrab zombies, after the Combine attempted to take over Eli's lab. Then he went along the coastal regions, fighting giant insect creatures. He went to Nova Prospekt, a prison where Eli was being held. He then went back to City 17 and fought the Combine in an all-out urban war. He finally came to the Combine citadel, where the leader of the Combine dwelled. He fought through the Combine forces until he reached Dr. Breen, his former employer who was now working for the Combine. He stopped Breen from escaping in a portal. Everything started to go to hell, explosions, things crashing and burning as he attempted to destroy the portal. Then he blacked out, and before him stood a man in a blue suite. The same man as before. He turned away and walked int othe black expanse that laid before him, opened a door, and walked out. And here we are, eagerly awaiting Half-Life 3.

The greatest scientist who has never lived.
I would really like to read Gordon Freeman's fake thesis entitled "Observation of Einstein-Podolsky-Rosen Entanglement on Supraquantum Structures by Induction Through Nonlinear Transuranic Crystal of Extremely Long Wavelength (ELW) Pulse from Mode-Locked Source Array."

2. I got locked out of the building, so I found the ventilation duct and Gordon Freeman'ed my way in.

Noun.

The main character of the Half Life video game series. He has a PhD in Theoretical Physics, wears thick glasses and can kick your and anyone elses ass without so much as breaking a sweat. He never talks, and doesn't need to, because he lets the high-caliber bullets careening into your chest do the talking for him.

After his first outing in HL1, Dr. Freeman had to escort and save a hot piece of ass named Alyx Vance, and also save the world and all that shit.

Dr. Freeman is the epitome of badassery. He is the perfect example of an awesome fictional character. He is Gordon Freeman. He will kick your ass.
Holy shit guy, it's Gordon Freeman! There's waaay too much badassness in this fuckin' room man! (explodes)
