Research and Development is a puzzle-centric mod for Half-Life 2: Episode Two featuring an unarmed player but plenty of violent mayhem.

The player has NO weapons and there is no shooting at all. However that doesn’t mean you can’t kill things, but 95% of the mod is about solving the puzzles that are presented to you in a very natural way.

AT 30,000 FEET… you are almost 6 miles (9.7 kilometers) above sea level. The human body is not made for these conditions. Temperatures are can plummet to -60F (-51C), the brain is starved for oxygen and each step is a new experience in pure agony. It’s difficult to breathe. It’s difficult to think. It’s difficult to move. And you still have to endure another 444 feet (0.14 kilometers) to get to the peak. So much for the good news.

A Resistance listening post suddenly goes off-air and you are sent in to find out what happened to the original support crew and get the station back online. Your journey begins as a rowing boat coasts towards the landing point. Who knows what you will encounter, both on the way up to the tower and on your way down.

You can play the Ravenholm mod now in preparation for the future episodic release of John’s travels, Eye of the Storm.

This release contains both parts but also allows you to start from the end of part 1. The Combine have destroyed the listening outpost and you managed to escape in to the tunnel, but don’t think you can just drive away, oh no!

You must help your fellow rebels out before you can put your feet up and have a cup of tea.

Plenty of beautiful views and deadly action.

As the name suggests Minerva: Metastasis : Parts 1, 2 and 3 contains all 3 parts of the Metastasis trilogy. I am writing this introduction without having found time to play the third part, so I can’t really add any useful information. If you are new this series I highly recommend playing it now.

You are Frank Harrison, a rebel, who lives near City 17.

You wake up and find that the Citadel looks like it is about to explode and those scientists are urging you to flee the city.

No need to tell you twice! Off you go and good luck – you’ll need it.

A story based mod that leads you through a variety of interesting environments to your ultimate objective.

This modification offers a multi-level side story of Gordon Freeman while en-route to City 17 via Highway 17 in the infamous buggy.

CSS SCI FI 3: Hardwired is a single-player modification for Half-Life 2. Waking up to find himself an augmented clone of Gordon Freeman, the player must fight time-travelling Combine forces and other enemies across 42 unique and replayable missions.

Missions are set in 18 retail and 24 custom Counter-Strike: Source maps, which are installed intact to the player’s CS:S game folder. The mod edits the entity data for each map as it is loaded, adding and modifying entities to create a seamless single-player experience. The maps remain unchanged and are fully playable in Counter-Strike: Source. Maps have been contributed by established designers, including Bluestrike, Schuzak and d00ds.com. Combat locations range from a snow-covered country church to a dense pine forest to a sun-baked tropical island.
