Favorite single player mods?

Half-Life Series
#1

I really enjoy Minerva and Precursor. What are some other good single player mods for either Half-Life 1 or 2?

#2

Research & Development and Nightmare House 2

#3

Underhell, Joutomaa.

#4

This This This This

It could even be a stand alone title, it’s the best mod I’ve ever played and very well done.

#5

I’m having an issue with Research and Development. I can only plug in one end of the cable for unlocking the door. The other one never reaches.

#6

It’s not really an issue. It’s part of the puzzle.

#7

Try and see if there’s any Extenze lying around.

#8

Black mesa is definetly gonna be nr. 1 for me. But until that its “Afraid of monsters DC” for hl1 it was really awesome.

#9

Your favorite mod is an unreleased one? Great troll.

#10

Afraid of Monsters DC. The best mod ever made for anything.

#11

Strider mountain mod for Half-life 2. Very, very long.

#12

I just played and beat Nightmare House 2. It was amazing.

#13

But very, very bad.

#14

I hate fighting striders, so I have zero interest in a mod called Strider Mountain.

#15

Its not my favourite one yet but i know its gonna be nr. 1 for me when i have played it. As i said Afraid of monsters DC. is my favourite one right now.

For hl2: dangerous world

For portal: portal prelude
