I have downloaded half life 2 but i don't have the episodes and i don't know what mods require the episodes because they don't always say it and i was wondering if i had half life 2 legibly from steam bought but i download the episodes from the internet will i be able to play half life 2 mods with requires episodes?
And does nightmare house remake require episodes of half life 2 or does it require episode 2 like nightmare house 2
And other famous mods that require episodes yes or no?

The Citizen
Riot Act
Resident evil mansion
