Yes synergy is very good coop mod to play with your friends, you can mount and load a lot source games , you can play thru hl2, ep1, ep2, and many custom maps.

I realy miss 2009 community when there were like 30 servers full of people...but they are updateing the mod still, its realy great.

Nightmare House 2 is good but the pipeline create some bugs on it,the zombies had headcrabs and some missing textures, but this a good horror mod if u want download it (remember what I say about the pipeline) u can go to wecreatestuff official page and get it: http://nh2.wecreatestuff.com/

to fix some pipeline errors read this disscusion:

You can play Estranged Act I. Yes, it's not perfect, but it's good.

1. Underhell = the best
2. Nightmare House 2 ($ourse 13 remake) = nice
3. Paranoia 1-2 [hl1 mod] = great
4. Estranged A1 = good
5. Lost Story = by the time i hope it's good game.
