Steam, Tracks, Trouble & Riddles (S.T.T.&R.) is a single player adventure mod, based on source engine (Orange Box) by Valve. It combines two types of game play: an adventure game with complex, 3D-interactive riddles in a fantastic environment and a simulator for track based vehicles.

Some kind of steam-locomotive like vehicles you will drive through an post-war environment. The final goal is finding a “secret wagon” and destroying a hidden nuclear-bomb. After a long journey through the guts of a huge Megalopolis you will end up ... ok, prepare for unforseen consequences ;-)

Human life was wiped out in 1962/63 after the (fictional) failure of the cuba crisis. Machines developed their own “architecture” adding weird stuff to the existing world of the 1960ties.
It is a fictional world which might have happened, if men has gone and only robots still existing in 2525.

Have a look on the website .
For more information download and read the detailed concept.

Vehicles like “The Handcar”, “The E-Tram” and the “SteamerTram” are actually compiled and presented in a demo video:

5 comments by peegee1 on Dec 6th, 2014

About two and a half months went by since the release of Chapter One.
But after the release is like before the next release: which means that this story is definitely not over. We are working on an update of Chapter One containing a long list of improvements, based on all the helpful comments and support here on, and elsewhere. We read all comments and they are very apprechiated. They represent a valuable input for our work and the ongoing project. So do not hesitate.

For me, peegee, just placing another mod or releasing stuff is the not the only goal. What counts for me is learning, having an experimental approach and leading this project into something new, weird, funny, the train simulator with that robot in 2525, a dystopic-fictional-history adventure and something i even do not know until this project has been finished. :-)

There will be a new Chapter One V2 (which is NOT Chapter Two).
It will come with a better behavior of the handcar, another interaction with that crane at the beginning, some more feedback in the pipe and valve riddle (a lot of players have solved it without knowing why) and a lot of other tweaks and bug fixes. One more puzzle will be implemented in Easy Rider's Model Railroad, involing a new shunter locomotive model shown here and in the images section.

This shunter is based on a real, small and rare locomotive called KA 4013 and served from the thirties to the sixties in Germany.

Have a big thank you for your patience and the playing, commenting, reviewing and leading us a good way to a better Steam,Tracks,Trouble & Riddles. Not to forget: Thank you for voting!

Hi friends,

have a short life sign here.

Actually I am working on the first chapter of the mod.
Some days ago I finished the first riddle, implemented the
Easy Rider character, who will help the player and serve him
with information needed for solving the riddles.

I had to learn, that this is as time consuming like building that riddles. Sound recording, adding phonemes in face poser, creation of special animations scripted sequences, choreo files were the battle fields of the last weeks.

Stay tuned! Thank you for your patience.

Sorry to answer so late,
no this mod is not dead.

The character developing needed more time
but it's on a good way. I was interrupted
many times by real life duties and jobs,
but we are on a good way finishing
the milestone 4 section.

Good idea, but not really good realisation, good face animations of robot, ordinary level design, unobviously puzzles and broken scripts in couple of moments.
