Stuck between a rock and a hard place, Gordon is forced to venture through a dilapidated, hostile environment in order to clear the tram line of an alien infestation.

Offering approximately 15-30 minutes of gameplay, Scylla takes the player through a winding environment full of deadly hazards and enemies. Your performance may alter parts of the level as you progress. Be sure to watch out for special NPCs; not all are obvious.

I’m Taking a Partial Sabbatical

Hi Everybody,

I have some surprising news.

Over the last few years I have felt increasing pressure running the site. Remember, in various forms, I have been running the site for almost exactly 13 years. That’s a long time. During that time I have spent thousands of hours working on it. I feel that I’ve done a pretty good job at promoting SP maps and mods.

Recently, it has felt more like a burden than a hobby. Every weekend is planned around streams and work that needs to be done on the site. Every week day, most my free time is spent doing something related to the site.

I need a rest. A proper rest. Not just a few weeks. Even during my “holiday” I felt obligated to check in and see what’s happening. That’s wrong.

I heard something on The Goldberg’s last night. Somebody said “I just wanna ride my bike and play video games”. And that’s exactly how I feel. It’s time for me to be a consumer not a creator.

I feel that I have been trying to promote SP Half-Life stuff alone, of course I haven’t, but that’s just how it feels. I have tried so many different projects, initiatives, ideas and events. Some have been mildly succesful, others failures, but at least I tried.

One of the reasons I renamed the site from Planetphillip to RunThinkShootLive was because I wanted more community involvement. Something more like LambdaGeneration, but that takes a lot of work and it never really had the effect I had hoped for.

The new RTSL Discord server has brought with it yet more hassle.

I have been thinking about closing the site for a few years now and over the past few months that feeling has become stronger.

Unlike last time, which was a reaction to a big problem with ModDB, I will be giving people and myself time to transition.

What The Headcrab! – Episode 20

Hello and welcome to What The Headcrab! Episode 20.

A few days earlier than a week, but as you probably know, I am off on holiday tomorrow.

This will be the last episode until Saturday 20th August.

I hope you can live without it for that long. Maybe next year, I’ll get some guest host to fill in for me.

As always, there’s a giveaway courtesy of A A Ron from and news from RTSL.

Anyway, let’s get headcrabing.

Holiday and London Meet Up

New readers may be surprised to hear I have a holiday away from the site. Well, actually, I have a few but mostly just for the odd day or two here and there, but the one in August is longer. I will be away for 12 days!!!

12 days of no updates or new posts. Well, that’s not strictly true. The Week XX and weekly poll question will be schedule, but that’s it.

I do check email and follow the comments, however, I avoid replying or posting if I can. We all need to re-charge our creative batteries.

I will be in the UK, specifically, London and near Portsmouth.

Every year I post details of my holiday and suggest a RTSL meet Up (used to be a PP Meet Up) and in all the years I have been suggesting it, it’s only ever happened once – in New York. Two people came to meet me for dinner and it was a lot of fun.

So, here goes again:
Who would like to meet me in Central London on a either Sunday 14th, Saturday 20th or Sunday 21st for an afternoon coffee?

For those that are really serious, I’ll give you my mobile number and we can Whatsapp to arrange things.

But please, please only say you are interested if you really are and can actually make it. My time is so short there and I have so many things I want to do, London Sky Garden, Royal Opera House: Bolshoi ballet, British Museum, friends, shopping, parks restaurants etc etc, that I don’tr want to waste time sitting waiting for people who won’t come.

5 Concrete Wonders – Real Theme

I have been planning this Real Theme for quite a few years but never got around to actually posting it.

Unlike other Real Theme post that focus on one location, this one is more about the material and its possibilities.

I love concrete, no really. Anything built with concrete, especially large unusual structures fascinate me.

With that in mind, I present to you a variety of buildings and structures for inspiration when building maps.

Identify This Mod 004

The Renegadist is looking for a mod. Can you help?

“So plain and simple I’m looking for an old Half-Life 2 mod, if this is in the wrong section feel free to move it since I usually never post on the forums.

Basically this was an old mod I played over five years ago that I have not been able to track down since which leads me to believe it was removed. I don’t remember much about it because it’s been 5 years since I’ve played it or longer but from what I do remember I’ll write down here.

From what I remember the main plot of the mod was that both the Combine and the Human rebels had formed a piece treaty and now both factions were against the player (Both Combine and Rebels shooting at you.). There were parts of the level that I remember playing, one of which took place in a mine shaft filled with zombies and rainbow colored water (This I distinctly remember), there was a farm or something with hay bales, and finally a chapter devoted to driving on a road in the middle of a forest in the HL2 Ep2 Jalopy. I believe the main crowbar was replaced with an Axe and if I remember correctly a few other weapons were different from the default Half-Life 2 weapons. There was a part on the forest chapter where you walk into a concrete building to press a button that did something, maybe to launch a rocket but I’m not sure. I don’t remember the name of the mod however I do believe a radiation warning logo was in it, or at least on the menu screen which showed sections of the forest road chapter.

I know you are going off of bits and pieces however the fact that the plot is so different might help with finding it, in the case that the mod was removed or deleted if anyone has the mod I’d love a download link for it. Other then that I can’t really say much more since I only remember bits and pieces of it, if anyone has any questions or anything concerning the mod please feel free to ask away. The Moddb community is huge and the amount of Half-Life 2 modders and fans of mods is huge, hopefully one person out there knows what I’m talking about.

Thanks and here’s to hoping someone knows what mod this is!”
