Metro 2033 free for 24 hours on the Humble Store

For ME?! Ahh, you shouldn’t have

The Humble Store is celebrating one year of existence and that means a sale. And since websites tend to give gifts on their birthdays rather than receive them, that also means a full free copy of Metro 2033 for everyone who shows up in the next 24 hours.

You have until 10:00am Pacific tomorrow to claim the game — just provide an email address on the Humble Bundle’s main page. Note that the offer is for Metro 2033, not this year’s upgraded Metro 2033 Redux. The original version is still worth checking out, though. Great atmosphere.
