“Retaliation picks up where Dark Operations left off. There will be no Xen or displacer in Retaliation. Action is the main theme. It will mainly be an encounter against military targets, but there is a healthy dose of aliens too. There will also be many sequences and a few puzzles [...]

“In the early 21st century the U.S. fight several anti-terrorist campaigns in the Middle East. Bickering in the world community over the morality of these campaigns eventually leads to the withdrawal of China and Russia from the U.N. Even NATO is divided and it soon becomes obvious that America’s only real support comes from [...]

About
A small map that is out of proportion, the screenshots may demonstrate that. basically the ceiling is way too high. Gameplay is OK, but as with nearly all small maps it doesn’t particularly engage you. To finish you simply need to reach the end of a corridor.

Well, that could be a brief description of what [...]
This is a slightly humorous mappack, consisting of 7 maps. You start the mod by visiting the toilet and then you go to your commanding Officer to receive your orders. Upon your return the base has been taken over by Black Ops. Save the base and even the money! Sounds like [...]
The The Xen Campaigns is a single player episode for Half-Life: Opposing Force. Included are 14 maps, some custom sounds, skins and some custom sentences.
Apparently it’s a remake of the second map from Doom II
A 3 mappack, that was supposed to be part of something larger. Work your way through a base, killing the zombies, grunts and special ops.
You are on a space station, when suddenly everything goes crazy and your confinement is over. Can you escape?
An old beta/demo with missing textures. It’s still playable and finsihing in the repair garage. A word of warning – it’s pretty hard.
Work your way through a space station and find the portal to escape.
Your helicopter was shot down near an airport. Find the plane and get out, then clean up the second airport.

Escape the base, not much else to say really.
