Attention passengers: We are arriving at "Chronicles Pack," the last stop on the Metro: Last Light downloadable content line. The fourth and final piece of DLC includes three solo missions filling in side stories that run parallel to the game's main tale. The pack also includes the "multi barrelled bicycle shotgun," a fan-created weapon that 4A Games was impressed by enough to toss in the game.
The Chronicles Pack is priced at the reasonable round-trip ticket price of $4.99. It's also part of the Metro season pass, which now includes all four pieces of DLC immediately available for $15.
