Sure Gordon Freeman taking on the Combine in City 17 is pretty cool. But what about a hard-boiled private detective taking on the Combine in 1920s Chicago? Throw in some Tommy guns, trenchcoats, and a gritty voiceover, and you’ve got The Burton Equation, a mod that turns Half-Life 2 into a noir shooter.
Don’t worry, it’s not all gunningdown gangsters: there’s plenty of sci-fi in the mod as well. Did I mention there’s time travel? There’s time travel. You may start out in gangland Chicago, but you won’t stay there for long. You can sit this fight out, Dr Freeman: Zachary Burton is on the case.
