HALF LIFE CLIFF NOTES
BLACK MESA INBOUND
Gordon rides the Black Mesa tram to work.
Gordon arrives at Sector C where he shlunks the carrier into the beam causing a disaster of epic proportions.
Gordon breaks his way out of Sector C and somehow finds an elevator in the sewers.
Gordon navigates an office complex along with the help of scientists and security guards (on second thought, only the guards helped much.)
"WE'VE GOT HOSTILES"
Demonstrating a serious oversight of human rights, the US government sends in troops to neutralise all life including Gordon, who by now is toting a shotgun.
Gordon must somehow get past three long, sharp, deadly, noisy, and ugly green tentacles.
Gordon must power up a train while evading a big blue thingy...
ON A RAIL
A more violent train ride than the first chapter.
Gordon is apprehended by soldiers after surviving an assassination attempt on his life.
Gordon tries to avoid being processed by undiscriminating machines.
Gordon questions the ethics of putting secrecy and national security above individual human rights.
Gordon wonders why this chapter is called surface tension. And then he looks up and sees da choppers.
"FORGET ABOUT FREEMAN!"
Gordon rejoices since it is revealed that the soldiers are retreating from Black Mesa.
Some lazy scientists order Gordon to power up some pumps.
Then, Gordon is sent into another world. How fun.
Gordon jumps from platform to platform reminiscient of a plumber wearing red shirt and overalls.
Gordon's path is blocked by a walking testis. (Seriously that's what Valve programmers intended it to be)
Gordon goes gunnin' and runnin' across the factories of Xen like some action film hero.
Gordon attempts to hold peace talks with the supreme ruler of Xen, but it all breaks down eventually...
Gordon declines his offer of employment and is left stranded on Xen, where he makes peace with the remaining aliens. With the death of the autocratic, warmongering ruler, Nihilanth, the remaining Xen population sets up a provisional government that holds democratic elections. Gordon eventually settles down and marries a vortigaunt and lives happily ever after. THE END
