Let's put it straight: Half-Life + Fallout 3 = Black Mesa D.C.
I always love to see stuff reimagined in different art styles, but even if you put the novelty aspect of it aside, this is just a genuinely good mod. Half-Life and Fallout just work together really well, for some reason. Maybe it's the retrofuturistic sci-fi feel they both have going for them. Back to the mod: it good.
I don't understand why this mod isn't more popular, it deserves it.
The level design and faithful recreation of most areas are really good.
Quality stuff.
