The first DLC pack for Gotham City Impostors is available now for the low price of free! The pack includes a new map, two new weapons, many new costume choices, and much more. Regular players will be happy to hear that matchmaking has been improved, and you can now join games in-progress.

Community challenges have also been introduced recently. From now until February 29, 2012 you can earn extra costume coins for every game completed, every 50 kills, and every 50 deaths. Kill 50 enemies before February 26 and you’ll earn yourself 1250 XP as well. Community challenges can be viewed in the in-game Feats of Prowess section, or on the game’s official site. There’s a lot happening in the city of Gotham today, be sure to get in on the action.
