HL2 is a story driven shooter split into 14 different chapters. Simply click the chapter name to view an in-depth step by step guide through it.

Point Insertion This chapter is your introduction into City 17. You step off the train bewildered and then you get reintroduced to a few old friends and a few new ones too. Don't piss off the Civil Protection Team!

"A Red Letter Day" This chapter will introduce you to literally all of the old crew from Black Mesa and take you to Dr. Kleiner's laboratory where you also catch a glimpse of his "head humping" pet, Hedy Lemarr.

Route Kanal Aptly named as this chapter could be considered as quite a pain in the teeth, this chapter introduces you to the canal levels in the game and gives you a taste of what the Manhacks are like to battle with.

Water Hazard This chapter involves a lot of time and fun on the "Mudskipper" (air boat). Also in this chapter you will encounter the Combine Helicopter. This is an adrenaline packed chapter.

Black Mesa East It's not quite Black Mesa Research Facility but it does the trick. This chapter is pretty short but it gets you re-acquainted with Eli Vance. You also get to meet Dr. Judith Mossman and Alyx's pet, Dog. You also learn how to use the Manipulator.

"We Don't go to Ravenholm..." Ravenholm was once a nice village but since the invasion it's become heavily infested with zombies and headcrabs. Keeping them all in check is Father Grigori, village priest turned "survivalist monk".

Highway 17 Here you'll obtain the use of the Scout Car and meet such characters as Colonel Odessa Cubbage. There'll be road-side fights aplenty, try and stay in the Scout Car and avoid driving off the end of the cliff!

Sandtraps Antlions thrive around this area, as do Combine Soldiers. The coast is riddled with "thumpers" though that will deter any Antlions. You will also have the pleasure of meeting the Antlion Guard here.

Nova Prospekt Nova Prospekt was once a prison for the most horrific criminals ever to walk the earth. Now, even more evil, the Combine have turned the old prison into a jail, torture and slaughter house. You know, just to make the citizens feel comfortable.

Entanglement This chapter is still based in Nova Prospekt but it is in the basement of the prison. Alyx is accompanying you for some of this chapter.

Anticitizen One The time has arrived, all the citizens have started to revolt against Dr. Breen and the Combine. You're right in the thick of City 17 and you must meet up with Barney at the rendezvous point.

"Follow Freeman!" Even more fun and games in the streets of City 17 as you continue onwards towards the base of the Citadel. In this chapter expect lots of fights with lots of Striders.

Our Benefactors This chapter takes you deep into the Citadel and with only a modified Manipulator gun you have to battle through a myriad of Combine Elite soldiers.

Dark Energy You now come face to face with Dr. Breen and you embark on a final showdown with your latest arch-enemy. He's trying to escape, you have to stop him.
