Outpost 16 is a single-player level for HL2:EP2 that has a cinematic, moody tone with custom voice acting, models, scripted sequences and music.
Yes, this mod have good music and models. But it's only ONE, short level, and not that awesome, how it can be able to be.
And I understand that it couldn't be longer (author just wanted to show his skills). But really, he is working in "id Software" right now? Sorry, but it could be better.
