Maps and mods that feature a squad scenario.
“Betrayal takes place after episode 2, and features Gordon and 2 rebel accomplices breaking into a Combine controlled prison. Hoping to use the mysterious re-emergence of Dr. Breen as a diversion, Gorond and his colleages attempt to rescue their imprisoned friends”
You and a small squad of rebels must fight of the attack waves of antlions and fast zombies.

A normal day in your Combine controlled apartment goes horribly wrong. Can you and your friends escape?
Author’s Note “Crimson Dawn is a single-player map made for Half-Life 2. The goal is to make your way in to the coastal city, and help your squad and the Resistance Force assault the cities’ Main Supply Depot building to cut off the supply route for the Combine. I designed, built, textured and lit the entire level.”
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.
After waking up in the rubbish, you realize you need to get across to the other side of town.
Apparently a plane awaits you that can take you to safety.
Work your way through the sreets and even some sewers, join with a few rebels and get to that plane!
Continue where Escape 1 finished. This time you get more rebel friends and even a rocket launcher!
That’s the good new. The bad news is that some of the mod is outside and it’s dark.
Watch out for those zombies!
This is a slightly more complicated sequel to Explosions 1.
Your objective is to reach the offices and enter the portal-type device.
Many obstacles block your way and the careful use of the exploding barrels will ensure your success.
A straightforward map with a series of rooms that finish with a final fight with 3 Rebels.

“Enemy forces have invaded and let loose their secret weapon – a giant robot! Escape while you can and formulate a plan to defeat it and save the city.”
“Tells the action packed story of a familiar soldier brought back to earth by the Gman for an unknown purpose. Use a Barnacle as a grappling gun to swing and pull yourself through levels.”
“You’re trapped! Zombies and enemy soldiers impede you, but you have to make it out. They’re both after you, so watch your back.”
The death of the Nihilanth threw the Xenian army into disarray, and the subsequent portal storms stranded many on Earth in the wake of Combine occupation.
After once more having to endure existence beneath the totalitarian boot of their cosmic nemesis, they have searched for a way out. Now, buried in the heart of a dilapidated university, they’ve found it.
You must make your way through different portals solving puzzles and killing anything that gets in your way.
In Rebellion, you play as Mandella, colonel in the Confederation, a powerful military force. At the beginning, you explore the mothership as you’re asked by admiral Spade to attend your briefing.
A small to medium mod with the player in the role of a Metrocop. Your objective? Escape from the base after all the Combine turn against you. You start with a four-person squad and face mostly other Metrocops.
In this Single Player mod you play the role of Jamil Lee, who is a young member of the civilian resistance, taken by the Combine and currently imprisoned in Nova Prospekt.

A weird level where you get jumped around various parts of a city, assuming you get past the Striders and Gunship. Good Luck.
Here is a medium length map that was submitted to a Snarkpit competition. You play as Gordon Freeman on your way to what looks to be certain death.
Author’s Note
“This map is just a short map I’ve created that will be the first in a series of maps I have planned out. It still needs some tweaks here and there but for the most part this is the finished version of the first map in the series.”
Story
You’re part of one the first [...]
You find yourself arriving at some sort of Combine facility. You are taken to a room where you are attacked. Next thing you know you wake up in a bin, presumably assumed dead.
Wasting no time, you begin to explore and you find two identical rebel twins who tell you exactly what you need to do, it’s just they tell you in Russian!
As in most mods, you don’t really need to hear what they say, just do what you do best; find and kill Combine. And so, starts your journey to Abyss!
Alright Gordon, the Combine may not rule our planet any more, but they still dwell in many areas. We have confirmed the location of a militia that is taking hostages. They are in a warehouse in a war torn city. They aren’t demanding anything so we better just move in…..
