Metro 2033 wasn't a breakout success, but it garnered a rather dedicated fan following due to its fantastic visuals, atmospheric gameplay, and unique setting. Fans will undoubtedly be happy to hear that 4A Games' follow-up, Last Light, appears to be doing well. Publisher Deep Silver celebrated the game's success in a press release today without offering any concrete figures. Instead, the publisher points out that the game is "significantly outselling its predecessor over the same launch period."

For example, on PC, the game has "more than tripled Metro 2033's worldwide sales over the same opening week period. And in the US, the sequel sold through "more boxed units in its first week of sale than Metro 2033 has managed lifetime to date." That's impressive--although do note that Last Light is available on three platforms, not two (2033 never came out on PS3). Finally, "across all formats worldwide, Metro: Last Light has sold more units in its first week of sale than Metro 2033 managed in 3 months."

Of course, without hard numbers, it's hard to really gauge how successful the sequel has been. Metro 2033 went on to sell over 1.5 million copies, and was "very profitable" for former publisher THQ.

"4A Games are honored by the reception our latest project has received," 4A creative director Andrew Prokhorov said in the release. "We are a small but dedicated team who are lucky to have been given the creative freedom and support to make the kind of experience we dream, as gamers, of playing. Our work on Metro: Last Light continues with new single player DLC, and we look forward to revealing future projects from the team. We want to thank all the Metro fans for support we have received."

Perhaps the team will soon be able to afford moving to a bigger, better office?
