Escape the confines of City 17 and strike a blow for the resistance!

As Dr. Gordon Freeman, you were last seen exiting City 17 with Alyx Vance as the Citadel erupted amidst a storm of unknown proportions. Now, in Episode Two, you must battle and race against Combine forces as you traverse the White Forest to deliver a crucial information packet stolen from the Citadel to an enclave of fellow resistance scientists.

Episode Two is the second of a planned trilogy of games that extends the award-winning and best-selling Half-Life adventure. Unique weapons, vehicles, and new creatures, friends, and enemies all make an appearance.

Hi everybody,

Update Time! Sorry, it took a while and we call it a beta version because there weren't a lot of playtesters avaiable. Anyway we believe that this update is worth playing and turns the old version into an obsolete status. (You may download them for if you are in a reminiscent mood).

The new Chapter One V2 (beta) is here:

S.T.T. & R. Chapter One V2 (beta)

A lot of recommendations and suggestions coming from the community found their way into this new version like the new control scheme of the crane in the beginning or the new gauges in the pipe riddle. We are really thankful for all the comments, reviews and votes here, on and on

Not only bug fixes but new riddle sections are waiting for you. One you will find in the first map and one in the last. Enjoy 15 new lines of dialog of EasyRider and Happy Jack recorded by Ross Scott. You can find some new Easter Eggs you can find if you are lucky. One was posted here in the video section some weeks ago.

Shunter Cockpit

The new Release Guide provides you with installation intructions and useful information about the control and the story background. A new Solution Guide (Spoiler Alert!) will be avaiable in the next days.

New Pipe Riddle

Next step (after the bug fix) will be Chapter Two of course. Again I beg some patience, because I intend to work with th new source2 engine. This tool is not yet in our hands (exept for the Dota2 world). But there will be some concept art from time to time. Maybe EasyRider has to say something. We will record that for you. Suggestions from you are welcome everytime.

Looking forward to your comments we wish you fun
with Steam, Tracks, Trouble & Riddles Chapter One V2.


List of Changes in comparison to the first version:

Overall: added more graphical details in the environment like trees, foilage and more props in all maps.
Removed several minor bugs and glitches.

Better control of the crane: will be controlled by keyboard and mouse buttons now,
not by clicking on the levers. Removed the unneccesary "Backward Riddle" in the crane hall.

Repaired the sound script file for environmental correct echoes and implementation of
EasyRider's dialogs.

Fixed the handcar issue when players were thrown off the handcar while driving in a curve.

Fixed the bug after the transfer table: Player can't drive the handcar backwards through the closed fence anymore.

Inserted one more obstacle after the transfer table.

Renewed the “Pipe Riddle” in the octagonal yard:
Added some guidance with sound feedback on the valves and two gauges which display the status.
Added numbers at the containers and tanks for better orientation.

15 new dialog lines recorded with Ross Scott.

Renewed the riddle at the tunnels, EasyRider welcomes you now instead of following you.
Fixed the bug in the subway station throughing the player out of the map when
jumping on the moving carts

Shorten the “Frogger Riddles”, player has not to run through so many corridors.
Added one more big riddle with a new shunter and new wagon models before
player is going to activate the tram.

Better skymap in the last map, player can't see "the end of the world" anymore.
Player can't jump over the wall and fall down to the bottom of the skymap.

I try to install mods, but the game does not recognize mods and load the maps but not particles, weapons or other models, no sounds, just keep the map of the mod with normal ep2 system, why is this happening. if anyone wants to help I can give more details.

Are you putting all the mod folders files into your half-life episode 2 folder? If so, don't do that. Put them in Sourcemods, which should be another folder right next to your account folder.

If Valve are going to make Half Life 2: Episode Three, they have got to make it full of revenge for Alyx's father. Like, to try and wipe the combine forces straight out of City 17, to make it a free city.

Then maybe a new threat?

This is just my opinion, so I'm not trying to make it be like that, but I would like it like that.
