We missed this the other day: IGN has first details on Blacklight: Retribution, an upcoming free to play sequel to Blacklight: Tango Down, the downloadable shooter from Zombie Studios. The graphics will feature DirectX 11 support through the Unreal Engine 3 and gameplay will include extensive weapon customization and armored mechs, among other things. The game's E3 teaser trailer is now available, and here's a bit:

Blacklight: Retribution is set in the same sci-fi universe as the original, with the many of the core mechanics of Tango Down, but it builds them into something that borders on MMO territory without making the leap. Players get experience and a currency for scoring kills and during usual gameplay actions. As players level up, they can spend points on a skill tree reminiscent of the sort of thing you'd see in an RPG. The currency can be spent to buy new weapons, armor and weapon customizations.
