It begins with Gordon coming to the Borealis with Alyx, they're running away from the Combine, and it introduces a new type of Combine enemy - the Sweeper. The Sweeper is meant to get rid of any attackers to the Combine. Gordon is running away from it, firing objects at it from with his Gravity Gun(upgraded) and then he comes to a small shack. A few rebels are there, they are discussing stuff. Suddenly, out of nowhere, the Sweeper turns into a Combine Super Sweeper, and it destroys the shack. Eli's Ghost appears, and he throws Gordon a Physics Gun, similar to the one in GMod. it is limited in the way it is used, it can only pick up such weight before requiring a recharge, so it should be only used in the battle with the Sweeper. After defeating the sweeper, Gordon runs into a crack in the Borealis. He has to use the Physics Gun to throw a large Combine machine into a Black Hole. Suddenly, after doing so, John Lennon appears, and he begins playing Baby You're a Rich Man, and the rest of the Beatles somehow jump out of the Black Hole. A Huge Yellow Submarine flies into the room, and Gordon says "what the christ" and then Gabe appears on a motorcycle, all while the Beatles are screaming "BABY YOU'RE A RICH MAN, TOO" and Gabe says "hop on were goin to mcdonalds" then gabe eats and the games credits roll, but the REAL FINAL BOSS is Paul McCartney after realizing he's not in the credits. You have to then get a Copy of the Beatles Rock Band, insert it into your Steam, and play the creidts on it and convitncxe paul its realy hl2ep3 s credits snd then you learn GMan is gordon from tHE FURURUTE.
