Opposing Force Birthday Livestream

As Half-Life 2 just becomes a teenager, the venerable Half-Life inches closer to a whopping 20 years since release! But that celebration is next year at this time.

However, its sibling release Half-Life: Opposing Force is turning 18 years old this very weekend, and we’re celebrating with a full Op4 livestream just like last year for HL!

I (Don) will be streaming Opposing Force starting Sunday the 19th at 1pm Eastern US, which is 6pm in the UK and 7pm in Central Europe.

The stream will be on the RTSL YouTube Channel.

Half-Life / Valve Memorabilia

It’s been a long time since I posted soemthing in the Reader-to-Reader section of my blog. I have been meaning to post this for a few months, but finally made the time today.

I present to you my collection of Half-Life memorabilia. I don’t own that much, partly becasue I can’t afford to and partly becasue I don’t want too many things like that.

Under each photo is a brief description, and if you have any questions just ask.

I may have a look for some other boxes of the games, might be nice to have the full collections, inclduing all the versions of HL2. I’m pretty sure I have the Half-Life Generations packaging somewhere.

If youa re wondering about the blue back in some of the photos, I keep all the stuff in that, which is a waterproof bag. I am terrified of them getting soaked in a flood (it does happen in my town but it’s highly unlikely – I’m just over-protective).

Okay, here are my photos….

The Science Behind Half-Life: Game Names

The idea of an article about the science behind some aspects of the Half-Life games popped into my head when I was listening to a physics podcast. It was talking about Zero-Point Energy and of course I immediately recognized the term.

I performed a quick search to see if somebody else had already written something and was initially disappointed to find somebody had. However, after scanning it and seeing the author say that the “Zero Point Energy” was just “a pointless quasi-scientific name that has no serious grounding in genuine physics”, I decided I would write my own.

Again, I am very pleased to announce the release of, what I am sure is without doubt, the most comprehensive walkthrough of Opposing Force available.

It was made possible by the writing and research of Stanley E. Dunigan and the formatting skills of William Barnard.

Together, we have created a PDF version that can be viewed both online and printed.
