Dealspwn: All in all, Black Mesa is an absolutely staggering achievement, and we wouldn't judge you at all for shedding a tear come completion. For every Half-Life fan, this must be an essential game to play through; for anyone who missed out, there's now a fresh chance to see what we saw back in 1998 relatively unmolested by time. It feels special, and though that's difficult for this writer to detach from overwhelming fandom, it's a huge credit to the modding team who designed Black Mesa. This isn't a George Lucas-esque spit and polish that dazzles the senses but sucks at the soul, there's love, sweat, and tears in this return to where Gordon Freeman's journey started. Make time for it quickly, before Borderlands 2 arrives. Considering it's absolutely free, you'd have to be completely bonkers not to.
